Get a catalog from West Marine and/or Boaters World & study the electronics section to familiarize yourself with brands, functions & terminology
I would not recommend a HH VHF as the primary radio (only a backup). Look into flush-mounting for security or remove the unit each time. Same with the GPS. Also get a good quality 8' VHF antenna
For VHF look at ICOM or Standard Horizon. For a combo GPS/Sounder look at Garmin
If you want specific recommendations contact Jim at BOE (board vendor). He will provide you with great info & he has great prices
