Start with bus use of reverb first. The bus should have the reverb set 100% wet. This will help you avoid the oft repeated mistake of getting too much level due to some dry amount coming in through the bus.

The individual track sends to the reverb bus should be 'post fader' so that when you mix down the level of the individual tracks, they also fade down the level it also fades the amount sent to the reverb bus so you don't have unintentional stuff coming through the reverb bus.

If you get to the point where you've mastered this, then move on to having potentially different reverb types on individual tracks.

But first, get the bus use down. There are more than auditory reasons for doing this - it will help to keep the CPU resource use down.

Another thing to keep in mind - there's usually not a need to send the full frequency content to reverb - it can really muddy the sound, so put at least a high-pass filter in front of reverb either at the bus or on your individual track sends if you have that flexibility.

Hopefully that makes sense. I think I owe you a mix as part of a commitment I made during FAWM 2014. If you want to send me raw tracks without reverb for a song (make sure you export them all with the same start point), I'll demonstrate the above with a song-style appropriate reverb type.
