In your other post, I saw that you were planning on putting the delay and reverb in the amp's loop. If that's the case, here's how I would connect it:
Amp loop send -> In 7-10
Send 7 -> Decimator In
Decimator Out -> Return 7
Send 8 -> Delay In
Delay Out -> Return 8
Send 9 -> Reverb In
Reverb Out -> Return 9
Out A -> Amp loop return
