help with ranger/rogue/fighter 28 point build progression

[hyperstaz]

This question has probably been asked before, but I've yet to find a specific build i can follow. This is one of my first toons, so the stats are not be ideal. Still, I'd like to lv it to 20.
Stats:
Strenght: 16
dex: 16
con:12
int:12
wis:12
cha:8

so far, I've got
1 lv rogue, 1 lv fighter, 5 lv ranger

Now i'm at a crossroad. From what I read on the forums, ranger 18 is no long as useful. Thus I'm planning on getting tempest 1, then alternate fighter and ranger levels till I have ranger 12/fighter 6 for tempest 2 and kensai 1. I plan on inserting another rogue lv to max out my search, disable and umd somewhere.

Now my question is what should my multiclass progression be? I won't have enough skill points on fighter lvs to keep up with my trap skills. And where should I insert the rogue lv to get the most out of it's skill points? (my goal is to use raise dead reliably, and i'm f2p with no umd items (ok, technically p2p))

ok, I did a bit more searching and it seems 12 fighter /6 ranger/ 2 rog is a much more popular build than 6 fighter/ 12 ranger/ 2 rog. Wouldn't skills suffer a lot on the fighter levels? Is there anything fundalmentally wrong with a 6 fighter/ 12 ranger/ 2 rog build? (I'm not sure how to calculate dps, but i figured exchanging 12 rang/ 6 fighter has better dps. How much more dps does another 6 fgt lv do?)
