As LianaThorne said, they're all meant to work together and there's no single class that favors Bard/Archer. If you just aren't interested in trying to tackle them all, then Carpenter (bows), Goldsmith (accessories), and Leatherworking (armor) will provide most (but not all) of the crafted gear that a Bard/Archer uses.

I would suggest starting with Mining and Botany first, though. That will let you gather most of the raw materials you're going to need for crafting and greatly reduce the gil expense.

If you haven't assigned your retainers jobs yet for ventures, I would suggest assigning your default two combat jobs so they can gather the creature drops you will need (skins for Leatherworking as an example). Gathering ores and logs is far less annoying than trying to gather skins. If you've purchased additional retainers, then you can mix what jobs they have between gathering and combat.
