Inner Primary seals and gaskets
Tearing into my inner primary to fix a leak coming from one of the seals. I know there are atleast 4, but the service manual doesnt break them all down. I found this parts breakdown, but only 2 seals are listed.

What are all the seals so I can cover all bases? Those who have done this job, while I am there, what else is a good idea to change? My one buddy says do the stator, all the seals (main shaft, starter shaft, not sure what else though), if belt is bad (but it seems good) now is the time because swingarm has to be removed...cant think of anything else though.
Also, any tips from those who have done this job are appreciated. I know its key to install seals in the correct orientation, and I'm being lent some of the tools needed for this.
Any help is appreciated!

If you are talking seals and things you can check or may replace for peace of mind: IPB seal, starter jackshaft seal, transmission shifter shaft seal, transmission main shaft seal, quad seal, 5th gear seal (hard one), sprocket engine seal and possibly the spacer, new inner primary lock tabs, primary gasket, inspection/derby cover gasket. I would tighten down shifter arm allen head bolt or even replace it with grade 8 bolt.

If it's a seal on your inner primary then I know of 3 on my bikes, 94 and 95 softails, starter jackshaft, inner primary bearing and the big o-ring that goes between the motor and inner primary.
My bikes also have two more holes in the inner primary where the chain adjuster bolts fit but they are sealed with RTV.
It would help to know the year and model of your bike.

You might find some useful information in a thread I created when I changed the seals in my 1993 Fatboy.

If it were me I'd only replace the seals that are leaking or that I disturbed during disassembly.

I just did this job not long ago on a 98 RKC. FIrst up, primaries are expensive due to special tools required for seal drivers and the primary inner race removal/installation tool. This is a big job. Not hard, just a lot of work. You need to sit down with the factory service manual and the factory parts manual and do some real studying. When you get a parts list together, take a look at the special tools you are going to need. They are all listed in the service manual but you can get aftermarket parts as well. Maybe someone will loan you everything you need like you said. However; you still need to know what's what.
There is no way on God's green Earth that I would do this job and not replace every seal I came into contact with, leaking or otherwise. Your bike is getting old and those seals don't last forever. You shouldn't have to touch the stator unless it looks/smells burnt. There is a big O ring around the inner primary in that area to replace though and 1 seal (if I remember correctly). A guy about 4 or 5 posts up listed all the seals you will need. I would also replace the inner primary bearing race not because it is shot, but because it likely has moved on the shaft. It is not recommended to reinstall this race once it's been used either so toss the old one. Plus, there are several seals behind it that should be replaced anyway. My race had moved quite a bit.
There are a few seals in the primary as well that need to be replaced. Look at your clutch plates and primary chain slider shoe too.
Do it right. You don't want to have to go back in there again anytime soon because of a $5 seal you didn't think needed replacing or you couldn't pop for the tool to install it properly and to the correct depth.
The FIRST thing to do is disconnect your battery. If you leave it connected and get to monkeying around in there, the starter can engage and turn the bike over.
