I would make the trade. you'll have back to back 3rd round picks, and 2 4th rounders - nice
as far as attack plan:
I am assuming that you have 2nd overall, by the fact you would be giving up 2,23, right?
pick 1 - probably Forte or MJD- you want a young stud who catches the ball - Turner is not a recieving threat
Pick 2/3 (3rd round)- if there is a quality #2 RB, grab him, though by this time there likely wont be, but you should be able to lock up two #1 WRs - like jennings/White/Wayne - type
pick 4/5 (4th round)- another stud WR should be available. And if you see a quality QB that you really like - like a McNabb or a Rodgers type - grab him, but don't fret if one isn't there, quality can be had later (I got Rivers in the 13th in 2 leagues last year - ended up #2 overall player). If not, grab one of those rookie RBs that you know will contribute this year and be a stud later (e.g. Wells)
so by this time you should look like this, by round:
3: RB or WR
sample of this would be - RB: Forte /WR Jennings, Boldin, Welker, /QB Rodgers
OR : RB Forte, D.Ward /WR Jennings, Welker/ QB McNabb
OR: RB Forte, Wells /WR Wayne, White, Housh
in any case, Not bad, eh?
But, a few questions - How many players do you keep? For how long? Is this the first year of it being a keeper league? how well do you know the tendencies of the other owners?
The key to a winning season is focusing on one opponent at a time. Winning one week at a time. Never look back and never look ahead.
