It's really ridiculous how many problems I have with my airguns...Anyway, my latest problem is with my used to be trusty Disco. Earlier this month I got some RWS chamber lube and put some on its bolt probe o-ring. Immediately after the bolt probe would pop up, usually just a bit, but sometimes all the way up into the cocking part. (Probably the wrong term there) It didn't seem to affect accuracy; a couple days ago I put 5 shots into a squirrel's head on a varmint target at 30 yards, so I just ignored it. But today I was shooting with one of my buddies and it seemed a bit less accurate than usual. So I came home and shot some groups...that were pretty much terrible. 1"-2" at 30 yards. But I also noticed that if I held the bolt down the group was much more acceptable. How can I prevent this? Do I just need to send it in to Crosman, or will they not accept it because it was likely caused by the RWS lube?
I also noticed it's been harder to cock. I'll pull it back and then about 3/4 of the way back it'll kind of get stuck and I have to pull really hard. Also, where can you get bigger o rings?

Sounds like spring bind. If you do have a RVA, turn it back out and then try to adjust it to see if that fixes it. Also remove the spring to make sure it isn't showing any signs of bind (bent spring), if so, you will need a new spring. You can get O-rings at the hardware store. Just take your bolt probe and the O-ring with you.
