Have Store Credit but don't know what upgrade to get next

I have a store credit of $200 but don't know what to spend it on, of course I will be adding money to it. Here is what I was thinking.

King Bump air stops (don't know which to get) have a 3.5 lift but prob go 4.5
(have king coilovers all ready)
Arb Twin Compressor/ Have the single but I don't really need it till I swap the rear with a PR 60. I am running a PR44 with the Arb lockers.
Switch Pro- Again don't need right now but will be adding lights in the future and rear Arb lockers.
Trulite head lights Heated (might as well)
or....

Personally I was thinking the Kings since I can sort of use them now.

Any suggestions.

I'd go with the Kings up front

Was thinking the same however don't know which one to get. Do i get the 2.0 or 2.5 Different in price is negligible. Then what length? Do I go with 2.5 or the 4? Decisions, Decisions.
