Level 80 Boost
The way it works, you can “test drive” any class at 80, with temporary gear, but you’ll be limited to playing that character in the silverwastes.
When you’ve decided which character you want to consume the item, you talk to an NPC, and he makes that character 80 for real, gives you a set of starter L80 gear (soldier’s stats) and you can go anywhere you like.
So my adive to you is to try them all out for a bit and decide which one you like best, then use it on that one!

Welcome to Tyria!
I would not use it (permanently) until I was quite familiar with the game and the Professions.
You really do yourself no favor by skipping any learning processes.
You can, however, try out each Profession at L80, to see which one(s) you might want to create permanently.
Good luck.
