When I get my first amp with an effects loop (also my first
tube amp, Carvin V3) I know I'm going to put an EQ in the loop just to sculpt my tone further. When it comes to using distortion pedals with an amp that has distortion, the question you must ask yourself is, what character do you want? When you put a dist/OD pedal before the preamp, the dist/OD will be coloured by the amp. For a tube amp such as yours, I'd suggest you not use too much distortion and just use any pedals as a booster if you like the Marshall sound (I never played through a Marshall I liked) because it's a tube amp and
tube tone is just plain better :P. Some people use pedals like the MT-2 (metal zone) with high gain amps but you can use only a bit of the grit from it and just use the EQ for a broader variety of sounds you get from you amp.
All actual effects like reverb, chorus and the like should really be put in the effects loop (personal opinion of course but experiment all you wish). The wah can go in either after or before everything depending on how you like your sound (some people use it after but I don't see the point) but would recommend before anything. Compressor, never used one so wouldn't know where to put it, same with the noise suppressor. Delay should really come after all your modulation effects but you can put it before any distortion if you wish a strange sound (think early KoRn. YUM!).
So my final verdict on this may not be that helpful but I would go with this.
Wah-OD pedal-amp in-effects loop out-EQ-Noise Suppressor-chorus-delay-effects loop in.
Hope that's somewhat helpful and you can fill in the other pedals where you see fit. Good luck.
