Your mount is a sidequest to do once you reach level 20. I dont think the bot can do this for you at the moment (unless you mesh it yourself).
In terms of equipment, i buy mine from the market board. You don't need up to date armour all of the time but you dont want to be running lv50 fates in lv15 armour.
In order to get the gil to buy from market board i'd suggest mining for shards to sell. Possibly other gathering materials sell well but i personally mine shards.
Failing that, once you register at your grandcompany you earn company seals. These can be exchanged for armours etc.
