The only effects pedals that don't sound good plugged into an effects loop are distortion and wah-wah.
I usually use my effects loop for delay and reverb (ever try plugging a delay in BEFORE your distortion? Ouch), or if you're after a Dimebag Darrell tone try putting a graphic EQ in your effects loop, followed by noise gate if you have one. Boost the EQ's high and low frequencies and cut the middles.
I prefer to plug phasers, flangers and chorus in the regular stomp-box way, into my amp's distortion channel, but that's personal preference. I don't like the way those three effects sound after distortion, too much like a keyboard or something. I like 'em grungier, Hendrixier.
Ultimately, just plug everything in as many ways as you can think of, because there is no right or wrong, there's only what you like best.
