This might be a dumb question, but where are the O2 sensors on the 06 touring models located? They should be on the exhaust right? When I was taking off the stock exhaust, there weren't any sensors screwed into it anywhere. I also tried searching my copy of the manual and didn't see a mention of O2 sensors.

Your 06 touring bike is not equipped with O2 sensors, so no auto tune is going to work because of it. You can add O2 sensors to the exhaust and then wire the bike for them and then add a tune that will allow the sensors to work, but that might be a little to much at your current knowledge level. It not real hard but it does take time and effort to do it properly.
Per Steves post. If the OP can find a competent Power Vision tuner, most tuners can add O2 sensors and complete the necessary electrical works and then tune.
My '03 was an early example of the Delphi EFI. Carb was standard and I ordered EFI as an oprion making my FLHTC into FLHTCI.
1st I had the Stage 1 Dealer Download which worked well with the stage 1 air cleaner and performance slip on mufflers.
Later I added 211 Cams and V&H True Duals so added the Power Commander USB 3 to enhance tuning of the TC88 with the piggy back tuner.
Later yet I added 10.5:1 High Compression Big Bore and changed from USB 3 to PCV and added the Autotune module. This configuration worked well for the TC95
Finally I added stroker wheels and bumped the original TC88 to TC103. There was virtually nothing out there in the way of canned off the shelf programs for my configuration. For this reason the Thundermax was installed.
With the Thundermax came a change of injectors to reduce the duty cycle of the stock injectors. Also Thundermax allows you to monitor AFR and let the AutoTune correct AFR for idle RPMS say 680 to 2500 which is great for getting the cold/warm start worked out. Beyonmd Initializing the Thundermax and establishing idle AFR the autotune does the rest. Ride and work all areas of %throttle, go home and accept the recommended changes to the fuel map. I believ it is limited to 1o points max adjust per cell per event so worst case 10 riding events and it is not making any significant changes.
As stated above my '03 did not have O2 Sensors. (My'13 originally had smaller narrow band open loop sensors) So I drilled my head pipes and welded in 18mm bungs 1st for the PCV Autotune 18mm Wide Band Closed Loop O2 sensors and later used for the Thundermax O2 Wide Band O2 Sensors.
Would anyone have any good resources on where to start if I wanted to add O2 sensors to my bike? If it seems doable, I might take a crack at it.
On the other hand, do you think the tune that would come on the PV for my setup would be "good enough" to get me back on the road? I know that if I want to really get it dialed in I'll need the O2 sensors, but I'm just really fiending to get back out there and ride. Just want to know what my options are
Just did a cam swap myself and have a Power Commander V already hooked up but thinking about getting the Autotune module. There's some good maps on their website but nothing that matches up 100%, I may just try a few of them out that seem close and see how it goes. I just did SE 204 cams so nothing too aggressive. Im hoping I can find a map that gets me where I need to be.
1st thing is to purchase the 18mm O2 Bungs. Then you purchase a hole saw, saw to drill adapter and I purchased an extension for the adapter.
Next you think long about how to get the O2's close to the head port while having enough room to screw the O2 sensor in or out and have an understanding of the O2 cable and how you would route it back to the Tuner Module.
Once you are sure you have the location, center punch the head pipes, and drill / Saw out the hole. Now you need to weld the bungs to the head pipes. In my case, I could only tack the bungs in location then removed the head pipes and welded around the bungs. After that its just a little more work to put it back together and install the Wide Band Sensors needed for AutoTune. I did mine 1 winter morning over a few cups of coffee.

My apologies... I totally missed that your bike was an '06, so it wouldn't have O2 sensors for a basic Auto tune session.
Steve Cole and others have given you good info about that...
FWIW...
I already bought and used my PV tuner on a couple of newer bikes with O2 sensor feedback, so on my 2003 Heritage, I bought a tune license and the Auto Tune Pro kit, which uses wide band O2 sensors. I already had a newer exhaust that came with 18mm bungs, which I capped for my application. That module allowed me to do Auto Tune Pro sessions on the pre-O2 sensor bike.
Back then I had to buy the additional license for my PowerVision ($200), then the Auto Tune Pro Kit (I believe was $400), and it helped dial in the HD Download map for that bike's original HD Big Bore Kit. I had it dyno tuned when I changed the cams. Those PV license & AT Pro Kit prices have gone up..

Also ensure where the bugs and O2's are located will still allow you to loosen and tighten the 2 exhaust to head bolts. This is a Pic of my O2 drill rig and where I placed them on my '03
