I installed the same fuseblock that MiTiempo posted. I can PM you a wiring diagram of my boat which is very simple and damned near universal. You can use or modify it as you see fit.
Miteimpo is correct on the VHF, BUT a hand-held with a stubby antenna doesn't have a lot of gain or range. You might consider buying one with a multipurpose antenna jack so that you can connect it to a larger, deck-mounted antenna. You still won't have to tie it into the boat's 12v system.
