Mackie for a board, Sennheiser has some goodwireless mics but make sure you rent a few over-the-ear mics before you buy.
OTE mics are very particular about the environment they are in and the equipment the signal is processed through. I use a DBX drive rack, graphic EQ, parametric EQ, and a compressor/gate to eliminate the feedback from stage monitors and get a clean sound from the mains. Some people need more, some need less, it just depends.
As far as speakers go, that depends on the venue size, type of music etc. I would suggest looking at some EV or JBL mains to start. They are versatile and can later be used as stage monitors.
