+1 & make sure the bit is all the way in & it's a good quality bit. I haven't striped a torx bolt in years using the proper sized quality bits. And don't use a drill!

When tightening the bolts, I just use the 5" handle on my wrench...and tighten by hand...snug, no more tight than you'd tighten spark plugs with the 6.5" wrench handle.
Notice I said ~100 inch pounds, not foot pounds.
Put a diaper or an oil pan underneath. And have the bike leaning on the jiffy...not vertical in a stand. Depending on how/who filled your primary case last with oil..the oil level they filled to, you will probably drip a little bit. More spill if bike is vertical in a wheel chock stand..thus the lean of the jiffy stand helps reduce amount of primary oil that may leak out.

secondly, do not go the dealer to have them torqued. that's just an extra pita step that you don't have to do. when you tighten them, just tighten them all to just barely holding, then go back and snug them all down, using a star pattern (upper left, lower right, etc). also, i find its a good idea to use a little anti-seize on the bolts so that they are easier to remove next time.
switch to allens if you want, or you can keep with the torx. i've only had one problem with the torx screws in 10 years, and that was after a dealer did my first service.
don't worry, you'll be fine.

You don't strip it taking it out - you find out it's stripped when you take it out. The stripping happens when you put it in and overtighten, but friction will often hold it until the next time you take it out and the little pieces of threads fall out.
The best way NOT to strip it is to use a tool for putting them back that doesn't give you a lot of leverage - for example, you can take them out with a ratchet torx but, but when you put them back, use a small screwdriver handle type driver to hold the bit, so you don't have as much leverage to help you overtighten.
Also, don't start thinking oil is going to leak if you don't crank them down - it isn't. I use my fingertips to tighten them, not my whole hand, and I've never ahd a leak. If you do get a leak, you can tighten some more. Remember to tighten evenly in a star pattern - I do the star 2 or 3 times, tightening a little more each time, so they are very even tight. I don't use a torque wrench, just feel.
This would be a good choice (in the correct size, of course):
