For gear, make sure to always get signet from the gate guard before you leave town. It is a protective spell that makes weaker enemies easier. It also allows you to get crystals (which you should sell in stacks of 12 on the auction house) and conquest points (you can use conquest points to buy gear from the gate guards) - just buy whatever gear you can from the gate guards - and the cheapest stuff you can find on the auction house for now. You can worry about getting better gear later.
Check enemies before you attack them. You should be aiming for "easy prey" for the most part, because your gear will suck and you don't have a sub job. There are floating books around outside. You should check them and do "training regimes" or whatever they are called. Pick one with the easiest possible prey abundant prey you can get exp from. I like doing the page with birds and saplings in the zone outside of the city. I usually camp by vomp hill (leave city from bastok mines). Once you've done a few pages and have tabs, grab the regen buff from the book.
Also there is a series of beginner quests your moogle will tell you to do, given by someone named Guldago I think in Bastok. Do it, it will give you a free exp ring, a reraise earring, and some beef jerky.
Tip: make sure you've turned "auto-sort" on in the options/configuration (or whatever) menu. It will save you hassle.
get yourself to 18 or so and join an alliance bashing skeletons in Gusgen mines. Make sure you get a magicked skull while you're there (ask to lot it, people will be cool). When you've gained a few more levels, go to valkurm dunes, and get a damselfly worm from the flies there and a crab apron from the crabs.
Then take those three items to an old guy by the water in Selbina. He will offer you a quest to increase your power. Trade him the items after he does so.
You will now have a sub job. A sub job can be equipped in a mog house or at a nomad moogle. It is a maximum of half your main job level. You get access to the passive skills, abilities and spells of your sub job when you have it equipped. You need to level your sub jobs separately from your main job

When it comes to sitting around not doing anything for long periods of time, only being active for short windows, and marginal changes and sidegrades I'd say FFXI players were the perfect choice for politicians.
