Need Help with setup and all my gear. What am I missing?

[DJHerb]

Hey all,

I need to know what equipment I need to plug in all my gear to work with Logic Pro. I am only used to using 1 midi controller at a time and I used to plug them in via USB ports.I decided it was time to go bigger and I have some extra money so I started buying new equipment.
.
This is what I have:

Imac
Logic Pro 9
M-Audio Midi Controller Keyboard
Korg Triton Extreme
NI Maschine
NI Traktor Kontrol S2
and some cheap Numark Turntables
VST plugins like Halion Sonic and such
Studio Monitors

I am looking to buy a DAW Controller Surface which has Audio Interface/Midi ins/outs, and Mic Pre amps. Should I get all those seperately or will that Controller Surface work best for my setup?

My Questions:
To use all this gear with my computer, what do I need to do/have/use? I think its just those things... the Audio Interface, Mic Pre's and more Midi Ins/Outs?
To get the Onboard Triton Extreme Keyboard sounds to record into Logic, what do I need to do to my setup? If I cannot do that. What is another way to do that?
I have a lot of experience using DAW's and Midi Controllers that are USB, the Midi connections and audio interfaces ive never dealt with.. So be easy. I'm hoping theres someone out there that can give me some information or suggestions on gear that would make all the stuff I have work in harmony with eachother. So what is it I need exactly?

What exactly are you trying to do? Record audio?

Check out the gear from Allen & Heath. The ZED-R16 combines an audio interface with a midi controller, it would be perfect for you. Its kinda expensive but from looking at your gear looks like you got some money lol.
