If you will have FOH reinforcement, I would recommend skipping the reverb and let the sound man deal with it. I've found that most clubs have enough ambience not to need verb on the stage, and in a very lively venue, it will just muddy up your sound. If you want to liven up the clean sounds on the amp...try a compressor.
For boost, I'd get an OD pedal that cleans up and has a lot of output gain. There are plenty out there. OD pedals tend to have a bump in the mids that will cut through the band. If you do go the boost switch, find something with a selectable high/mid/full range boost. Putting a treble boost in front of a distorted amp is better than a full range boost, which will muddy up the low end, and a mid boost would be used for a lead boost.
Can't speak for a noise gate...never used one. A guitarist in one band I work with has the MXR Noise Clamp. He likes it. You could always wire up an a/b switch with the b side disconnected, and use it as a kill switch to cut noise between songs.
