A cam is usually one of the BEST way's to improve the overall power of a motor (all RPM ranges are effected) where some mods just move the power band higher up the RPM range. The negative side effects can be: worse idle (think muscle car, womp womp womp, i had a high lift cam in my 3.8 wow nice difference), lowering overall milage, longevity of the motor if using an extremem cam (not likely in a civic i wouldn't think), usually the requirement of premium fuel.
I haven't done a cam in a Vtec motor before so i don't know exactly how well these react as my previous experience is on pushrod motors. Usually a cam was done later on after all the smaller mods are done.
