IMO forget buying a board boots and bindings initaly and buy yourself good kit. The quality of boards available for hire abroad is high, and you dont need to worry about trashing them when you crash into other boarders skiiers etc.

What time of year are you going, as this will have an impact on what layers you need for underneath?

Andora is a good choice for your 1st Boarding trip, am sure you'll have a cracking time.
