Your meter is your most important tool when doing lighting. You need to check the voltage at EACH lights connection to find what you are drawing - ideally you want to be around 11.5 - 12.5 volts(roughly). So if at the connection you are drawing 10 volts on the 12 tap then you will need to move to a higher voltage tap- in this case probably 14 volts.
The taps allow you to increase the volatage going into that run to compensate for voltage drops from lengh of run.
In your situation I would probably run 10-2 runs to the lights. 12-2 is a little small for what you will be drawing. It will save you headaches and allow a little bit of expansion on the run for later date. We use 10-2 almost always it is only pennies more than 12-2.
Hope that helps
