Good move stocking up on wideouts and running backs. You got good value at WR and plenty of options at RB.
Chris Johnson is my favorite of your guys. CJ1K is so last year, CJ2K is back. One of your other guys should be a decent RB#2, although it will be a tough decision week-to-week.
As to your wideouts, I'm really high on AJ Green as an upside pick and Jennings as a consistent scorer. You might be a little thing here since you have to start 3 WRs, but you should be okay if you keep an eye on the waiver wire as somebody will emerge.
Peyton is a big gamble in my opinion, but he will be at least startable if he stays healthy. Luck is a nice backup, good upside.
I would look to the waiver wire for another TE. In my league guys like Greg Olsen and Martellus Bennett (AKA the black unicorn) are available and have potential.
I'm also looking for feedback if you could: viewtopic.php?t=518441
