Flute. Don't panic. There have been reams of posts written here about indoor basketball photography. As you are discovering, this type of photography is an art, not a science. 3 Years ago, I started out with an XTi. I upgraded to a 30D about 18 months ago, and then upgraded again to a 40D about 6 months ago. I shoot mostly outdoor in farily poor light, so I can provide some insight:
1. AI Servo is what you should be using. Keep to it...
2. Based on my results and what I've read here about indoor basketball, try shooting in RAW only, and start experimenting with PP in Adobe Photoshop. That has really improved my photography.
3. With your 85mm, try to shoot only action that fills your frame. The first two images are nice, but a bit too far. From similar posts, it looks like the best stuff is shot from under the basket.
4. Invest in a monopod (if you don't already have one).
5. I would like to see you move yourself under the basket, only take pictures of action right in front of you that fills the frame, shoot in raw, and practice your PP in Photoshop.
Keep at it and don't give up...
What??? Shooting RAW is NOT required. I shoot 4 or 5 games a week from HS to pro events and never, ever shoot RAW. Learn to properly expose your shots and JPEG is all you will ever need (OK, almost all you will ever need - once in a blue moon I will shoot RAW+JPEG under very, very challenging light). And certainly don't shoot RAW with the assumption that you'll fix it all in post processing (or as the OP called it "bringing them up"), for the love of all that is holy! If there isn't enough light there to shoot the stuff, either add more light, or pack up and go home! You can't make the light bend to your will - if it's not there, the photos won't turn out.
Plus, I can't imagine how goofy one would look holding a camera with an 85 f/1.8 lens on it attached to a monopod. Why in the World would one need a monopod on an 85mm lens?
I agree that shooting tight is a good idea, but you can also crop a bit tighter if you shoot a little too loose. I don't happen to like the focal length of the 85 for basketball - it's too short for me.
There is some info on shooting ambient light in the second episode of a podcast here:

I know the author and he's working on the next episode which will be about strobing and flashing indoor sports. One hint: don't use HSS, please.
flute, David gave you some decent advice, and Tom Witte's site and of course Strobists are both excellent places to read about using speedlights to light gyms.
As for getting "looks" walking into gyms with a lot of gear, if you look like you know what you're doing (and have pre-approval from the school's AD and/or Principal) you might be amazed at how few questions you'll get. I strobe gyms several times each week and very, very rarely am even questioned about it.




BUT it did give me hope. I will work on that flash today and see if I can get it working again. If not, would it be entirely out of the question to trigger the speedlight with my onboard flash (gasp!)? I'm concerned about strength, light color and direction (I was bouncing the externals).
