Help My Chumps...

[My Chumps]

My chumps are struggling, and so am I.
2 trades left, 53 grand, and into the prelim in the only league I (really) care about.

The team is:
DEF: Gibbs, Goddard, Fisher, Deledio, Broughton, Grundy, NEWMAN (A Johnson, B Jacobs, J Toy)
MID: Boyd, Judd, Swan, Yab, Hodge, Bartel (S Iles, Tendai!, J Irons)
RUCK: Cox, Jamar (Vardy, McAuley)
FWD: Pav, Goodes, Buddy, Sylvia, Riewoldt, Riewoldt, Higgins (Darling, Richardson, Siposs)

Bit of trouble, I am aware.
My melbourne duo of Jamar and Sylvia have caused a bigger headache than a Barry Hall punch to the snozz, Newman's still out (any news?), my forward line is about as quality as Scotty Lucas' right boot, and I still have Gibbs and Juddy's byes to worry about.
First question, do I play Tendai, Sylvia or Higgins?
Second Q, Darling or J Roo?
Nemero 3, do I trade Newman?
Thanks guys.
