How to connect equipment

I have a good mic and a nice tube preamp with adjustments for gain, impedance, filter, limiter and phase and it provides a rich, warm sound.

I'm still having some problems setting up, though, and I would really appreciate others' expertise. I'm missing something in my understanding - so perhaps I need more detailed instructions - please be very specific and use my words in your reply so I can follow. (Also if the 1/4" needs to be specifically mono/stereo)

Mic preamp XLR in and out; 1/4" in and out

Mixer (Fostex 8VL) has the following inputs/outputs:
L/R Mono Aux returns 1/4" (2 sets)
1 and 2 Aux send 1/4"
L/R Mono Out 1/4"
L/R Stereo Out RCA
8 Recorder OUt RCA
2 DAT ports
1 Punch in/out 1/4"
2 MIDI ports
8 1/4" track inputs and a headphone input for the master fader in front

Computer: line in and mic in

Effects processor has 1/4" in and out

Compressor/limiter has XLR in and out, TRS in and out and Key Ext. TS send and return

Thanks so much for your help.
