If you want someone legit to answer your questions...
I was iffy on TO to start the year(have him on none of my teams and I am a cowboys fan) so no I don't really expect him to finish top 5..if he wasn't top 10 WR though I'd be a bit surprised.
If this is a 10 team or higher league you got alot of good trade bait.
you have 4 good RBs, 3 solid WRs
Honestly a very good team.
Barber I expect top 5 from and Calvin I like as a number 3. He will be inconsistant from week to week most likely but the potential for what he can do is worth him being a number 3(for example what he did this past weekend lol)
