I don't know about pricing info, but some of those TI games are fairly rare. All in all, you got a really good group of games!
I agree, that's a nice mix of games for the TI! Tyranthraxus is correct about the Digital Press guide, its prices can be off a bit from current market conditions, but all in all I think it's an excellent resource (and a pretty fun read). It can be found on eBay for a BIN of $25 at nearly all times.
Among other places, there is a fairly-complete looking TI rarity list at:
http://www.99er.net/rarity.html. Obviously, the best indicator of value is to see what these things have sold for in the past - searching completed eBay auctions is an OK (but by no means perfect) way to establish approximate value.
Don't expect a lot. A game like 4A Flyer is pretty uncommon, but it still only got $12 on eBay. Here is the link to the completed auction:

The TI market isn't too dynamic, it's really a collector's market right now. Same goes for the C-64 market, in my opinion. That may change in the future, but for now the fun is in playing the games, like Steve said. Or if you find a diehard 99'er, items like that may be nice trade material.
