I got my knee sleeves for $25/ind off ebay. I've had them for months now, and love them. Be careful not to use them all the time, try to use them for warming up and heaviest sets.
Rows in TM are meant to hit back/shouldaz/trapz. Cleans aren't really a good sub, because they are an explosive movement and shouldn't be done too late in the training day. That said, if you must clean in the TM programming, keep the reps low (1-3 range, no more than 5 for work sets), and do them first as a good way to warm up your hips.
Balancing Oly lifts into another program (in your case, TM, A-pie) is a really tricky thing. It is really easy to stifle #gainz with too much oly, which is very common. Don't just sub them for non-Oly movements. Spend some time on google, looking at good programs to combine the two styles. It's a bit advanced, but spend some time on The Outlaw Way, which is part of the Outlaw Crossfit gym in Alexandria, MD; their hybrid programming is about as good as anyones, but it is a ton of volume.
I can't stress enough that you should spend some cash on some private sessions with a coach, working on your oly lifts. Clean, Clean & Jerk, and Snatch. I can help a bit, if you post videos. If I'm not on here for a couple days, email me at my rcf handle at hawt male dot comm.
