That is 100% up to you! You can decide between Republic/Rebels or Imperial/Empire. In these you have the following for each faction to chose from:
Republic Faction:
Jedi Knight
Jedi Sorcerer
Smuggler
Soldier/Trooper.
Imperial Faction:
Sith Warrior
Sith Inquisitor
Bounty Hunter
Imperial Agent
Its a personal preference, but I have the best time in game play using the scout class, the soldier and scoundrel both are extremes in two different directions, limiting their abilities, but the scout is a balance of the two.
You can keep anything you find in SWTOR in your inventory or your bank vault. Wheather or not you can use them, is totally up to the class you play. Troopers use rifles and autocannons, not melee weapons.
