If you are interested in self-sufficiency then you should level cooking to the highest and alchemy to 60. Other crafts are better to be postponed till 100.
When you start leveling professions the most strategic choice to make is whether you want them all on one char or make several alts for that.
Same char. Pros: faster leveling since you need to learn setskills and badge titles only on one char. Cons: you may have to buy craft expansion tickets to bypass the limitations.
Different chars. Pros: This is cheaper (most likely). Cons: leveling will take more resources and time.
There is basically only one way to progress in any craft. Namely, making items. The trick is to get most exp of it. So make sure to get every possible buff for this. Badge titles, crafting exp potion (can be bought with phirius shells), using crafting stations placed in residence (buy it yourself or ask your guildies, someone may let you use his), learning item-set skills for production exp and speed. Using craft speed potion from daily gifts is a good idea for saving time.
Making items will require resources. You can buy them with mementos or wait till crafting festival and spend only gold till 90 or so.
After you thoroughly research and learn what it takes to level one profession to 100 you will decide that it's better to be postponed till reaching level cap, getting at least some gear and running instances. And this will be the right decision ))
The bottom line. Don't bother much with crafting at start. Use dirty statted gear when you are leveling. After 65 or so buy or lend weapons, rings, necklaces that were top grade at lower caps.
And when you are 100 don't go for gear lower than crafted rank. The reason is simple. The price of the item itself sometimes can be literally negligible compared to improvement costs. Making gear isn't free. Actually it's gameforge's most powerful vacuum cleaner to empty your pockets. Yes, this is a pay-to-win game in case you haven't noticed this yet.
PS. Normal mode gear is same rank as crafted, memento gear is between shell and crafted and you should not be spending your memento for it.
