Unless your system is incredibly busy, or your SSD is very full all the time, I'm not sure doing trim operations other than at idle is actually a good idea. This will only come into play if you do keep the drive both busy and constantly near full capacity (with non-static data changing regularly) all the time, honestly. I've got some 830s, and a few variants of other drives based on Sandforce controllers, and I've not found any issues at all with performance that would come back to being TRIM-related. I have found 240/256GB and larger drives perform better than their smaller counterparts, but there's a good reason for that. I choose larger drives as well to avoid having a very full drive which can indeed impact performance if the contents change regularly (static data wouldn't be much of an issue even on a very full SSD).
