6. How do most people make money? Do you earn significant amounts of gil questing to support buying upgrades or should i level up crafting a bit and sell some things to keep my money flow up.

Doing levequests and your main scenario quests both provide nice gil rewards. Apart from that, gathering materials, farming materials from mobs, and crafting items, all to sell. Keeping up with your main quests and doing your guildleves should provide you with enough gil to get any DoW or DoM to 50, from there you have more options, including the ability to continue in leveling parties to convert gear into materia, which can be very profitable.

There's this thread on the FFXIV reddit that also has some tips.
