what up man, thru reading numerous posts of yours and replys to everyones questions I feel that you know a bit about car audio

I need some help.
FYI- I have a 98 Accord Sedan EXL
Not to long ago, I purchased the following:
Pioneer avx7000
Pioneer p900r
Infinnity Perfect Componnents
Infinnity Kappa 3-way 6x9's
Infinnity Perfect Subs (2) 10"
Kicker 2252 Amp (=componnents)
Kicker 1252 Amp (=3-ways)
Zapco AG1000 Amp (Subs)
Ive been saving some green to get a custom install complete with vinyl wrapped custom spare tire box (firing towards the license plate) and flush mount amp racks covered in plexi, exc exc. Well today I went down to my local shop and I need to make some decisions.
1. Ported or Sealed Box
2. Is it worth paying a **** load of money for RCA cables? I had a PG and a Stinger to choose from one was 10.00 and the other was 50.00 does it really fvcking matter? I want a clean looking install anyway with the wires run under the amp.
3.What gauge of wire should I run?
ott,4,8 and to which amps? For some reason I thought that the shop would do whatever was the most expensive, considering I know no better. I dont want anything that i dont need.
4. I was told that tweet an mid range speakers are supposed to be mounted within hands distance of eachother (componnent set with tweet and 6 1/2), so are my componnents going to sound like sh!t if I put my 6 1/2 in the doors and my tweets in the factory location up under the windshield? If so should I invest in Kick-Panels?
Sorry for all of the questions Bro I just wanted a second oppinion, from someone that isnt going to profit on there awnswers.
