LilSprocket, the meniscus tear isn't that bad an injury--assuming you have the more common type! I had one a few years back and wish I hadn't had the surgery.

My $0.02....if you have the tear and decide to get it repaired, make sure your quadriceps are as strong as you can make them before having it done. Many folks I know have had it done (we all play Ultimate Frisbee, which is hell on your knees) and many of us developed patellar tendinitis either because of the tear or the recovery from the surgery. Having really strong quads will help prevent that (and help the tear itself).

Here's hoping you don't have it!
