I am looking to put a little more money under my hood somewhat soon. Please give me a few opinions on my list and heck, maybe add something.

drop to either a 3.2 or a 3.0
slp headers
3rd gen LSD
colder plugs and new wires (really need help here)
tensioner pulley
high flow cat (not sure about this; depends if it will pass emissions)
possibly even an intercooler, mainly if i decide to go with a 3.0

current mods are: 3.4, FWI, 1.9:1 rr'*, or rods, LS6 springs, autolite 104'*, PCM

I hate you...

Aim intercooler. Once you are ice cold tons of other things can be built on top for lower cost.

Well, I can comment on the plugs and wires, and the cat.

the hi-flow cat should pass emisions just fine.

As to the plug question, Rogue most recently answered that one here:
Spark Plugs and Wires

I'd def. go with the intercooler instead of the LSD. The intercooler will not only unlock some power but it will also give you a little safty to protect your engine. Their are many people putting out 300+ FWHP with 1.9'* and a full-sized I/C.

IC / 3.0 / headers / tune = pwnag3

doesnt anyone think traction will become an issue though?

Traction will be a result of the intercooler..

Currently he probably has enough traction to be happy.

how'* an i/c going to provide traction? i'm definitely not happy with my traction right now. i dont have much. i was even thinking of going to DR'* or slicks if i do decide to go with more power

I heard about your driving Ryan...lol...

I meant traction loss would be a result of the IC

Ryan, you WILL need DR'* or Slicks, PRP does a good job preping the track, but your 60'* are gonna suck on street tires
