I think inconsistency is the definition of why players are RB2 or WR2's instead of 1's, but I still understand the frustration. That said, I would not be looking to trade Wayne, I actually think he's a buy-low guy right now given that he's putting up tons of yards but not showing up as a fantasy star just because the TDs haven't gone his way of late. They'll come eventually, and you'll be glad you held on to him.
I do agree that trading LT would be well-timed if you could find a taker for decent value. I'd look to get a second RB to pair with CJ if possible so that you've got Felix either out of your lineup or at the more appropriate "flex" spot for him.
Otherwise, I think you probably will do fine standing pat. I mean, you have a lot of guys on your bench that are high-risk high-reward at the moment (R. Bush, V. Jackson, etc.) and if one or two of them show up during the playoff weeks for you you could be really, really solid. Especially with the knowledge that you're in first place and thus have the luxury of being patient, I'd wait it out.
