I have never seen a definative 'list' as such. The obvious things like Belts, rockers, valve clearances etc are all done at your 24 month service, and providing they are done correctly, you shouldn't even give them a second thought until the next service.
I guess the things that you want to know are common problems...things that can go wrong:
Check your reg/rec connecting block for signs of damage/corrosion.
Check your rear hub area for signs of the hub chewing into the ally collar.
Check your fork and shock seals.
Coolant reservoir can crack and leak/spray coolant.
If you are doing oil changes yourself...check for partcles in the drained oil and the guazes (see shazzams great post on this recently).
Check the clutch basket for signs of excessive notching every now and then, and whilst you are at it, check the plates and clean it out.
Do a general nuts a bolts check as the vibes of a v-twin can loosen a few. I happened to check mine and found three of my four subframe bolts loose.
To be honest most other things are common to all bikes and I give mine a good look over whenever I clean it...for example give mag wheels a good look over for any road damage, check chain tension as incorrect tension will not only give you a poor ride and bugger the chain, but it has a dramatic effect on how well the bike selects gears/neutral.
The main thing is really to get it serviced, particularly the big 24 month one, by some you trust or comes highly recommended...as they will check these things out for you and should notice many of the above.
But don't get paranoid about it...my first 748 needed a little care and attention to get it to a great condition, but once there, it did me good for several years. Looks like the current bike is going to be the same.
