Right or wrong I think Thole, Valencia, Reimold, and Francisco are locks. With the way Goins is playing I would like him up (no qualms if someone would rather have Kawasaki) and if it were up to me I'd consider expanding the bench to 5 and keeping Gose up as well.
If Goins continues to hit the Lawrie 2B/3B platoon could be as follows:
vs. RHP:
3B: Lawrie
2B: Goins
Bench: Francisco, Valencia
vs. LHP:
3B: Valencia
2B: Lawrie
Bench: Francisco, Goins
The other way to do it is to just have Francisco and Valencia straight platoon at 3B with Lawrie at 2B.
