So, what exactly are you trying to "learn" from renting a lens? You have 50mm with your Sigma and 85mm with your Tamron, so you should be able to get a "feel" of those two focal lengths, although they will have a different field of view on a full frame. So really, zoomed out to 50mm on your T1i will be similar to shooting at 85mm on a full frame.
As to the lenses that you are considering, well, they are all good quality and obviously with the wider apertures they will be "faster" in low light, so if you don't use a flash for indoor shooting then any of them will be an improvement! However, I'd have the flash ready, 'cause if the light gets too dim then you are stuck shooting wide open without a flash, which may not be as "nice" as you would think!
I guess I'm just looking at this as an opportunity to play around with a full frame camera; a different setup from what I'm familiar with. At some point, I would love to buy a MII or MIII but I don't have the cash to drop on one right now.
I won't really need to "learn" anything as far as the focal length goes, I don't think. I'm used to the focal ranges of the lenses I'm looking at. The main issue with my Tamron is that I can really only use it outdoors on a sunny day. I just can't open the aperture up enough to get good results indoors. I can use it wide open, but it's soft wide open and bumping up the ISO leaves too much noise for my taste typically. My 17-50 does a pretty good job indoors, but I like to stop down to f/4 or so because it seems that's where the sweet spot is on that lens, so indoors, I still need a flash a lot of times and to be honest, I'm just not that good with a flash yet. I can mess around with it enough to get an acceptable (in my eyes) result, but it's not as good as it could be in experienced hands. So, I figured I could rent a MII or MIII which has much better ISO capabilities than my TI1 paired with an f/1.4 or so lens and I should be able to get some great shots indoors without the need for the flash.

That may be, but if you're shooting a B-day party, I'd want a 28 or 35mm f/2 at hand, too.
Good point, I guess i could rent a really wide angle as well as it's not that much more money. Would be nice to get some wide family shots. Of course, I could always use my T1i along with my 17-50 for that purpose and it would be fine I think.
