Great post! I just wanted to add a little bit about gardening. You can look up recipes on
Pikko's Pots. These are not guaranteed, as all gardening recipes have a random element, so there is a chance of growing several different things from the same ingredients.
First, buy 1-10 pots from an NPC in one of the starting cities for about 1000 gil each. (You can have up to 10 in your mog house, but I recommend starting with 2-3 until you know if you like gardening.) Next, put them in your mog safe. Select Furnishings from the Mog House menu (can only be selected in your home nation). Select Layout, and place your pots in your mog house.
Next, buy or farm some seeds. I recommend starting with vegetable seeds, as they are not as expensive as grain seeds, and they only require one crystal feeding. Later you can grow tree saplings from tree cuttings. You can grow elemental ores from tree saplings, but don't do this until you have a lot of gil to play with. Results are not guaranteed, and there is nothing worse than spending 100-200,000 gil, waiting a full real-life month, and getting nothing but cinnamon. (No, I'm not bitter. ><) You can also garden with Fruit Seeds and Cactus Stems, but I haven't tried these.
Place the seeds in your Mog Safe. Select Gardening from the Mog House menu. Select one of the pots from the list and select Plant Seeds.
Try to examine your plants once per real-life day. Eventually, Moogle will tell you your plants are not doing very well. This means they are ready to be fed a crystal. The type of crystal is part of the recipe. Some recipes do not use a crystal. Don't let Moogle worry you, your plant will be fine! Just continue checking it as normal, and eventually, he will tell you your plants are doing well again. Side note - if you do not feed your plant a crystal, it will grow a little slower.
After awhile (about a week for vegetable and grain seeds), Moogle will tell you your plants are ready to harvest when you check them. You will also notice they are glowing. Very pretty. Be sure to select Harvest, not Dry Flowers. Drying your flowers will make them a furnishing, but you will not get anything from them. The items harvested will go in your mog safe, so be sure to get them into your Items before you go to the auction house!
I started gardening at about the Dunes level. It's great for any level, and you don't have to spend any gil to skill up. As you get more gil, you can try different kinds of pots and some of the more expensive recipes. If you decide you want to try growing ores,
Ariah's FFXI Garden is a great place for tips.
