Garrisons really don't affect leveling characters all that much if you're actually leveling them. You will get more resources just picking up treasure in zones as you level, and any resources you get can quickly evaporate if you try to build your base up too much. Definitely grab an enchanting hut and any other prof for small, and a trading post for medium. Lumber yard is nice but requires too much work for lazy players like me, and the trading post is a money making machine if you keep an eye on market prices and the current vendor. I like to get a bunker (war mill) for the ilvl bumps while leveling, but don't get it until you have a good chunk of spare resources. Upgrade your mine and herb garden to their max asap, they can be tedious but give a steady supply of income and XP if you're active.
Oh and about those books you get at the end of major questlines that you can trade for blueprints: You don't have to pick a building right away to make use of them. The blueprints sell to vendors for the same price they cost, so I usually just consider those quests as a 1k gold or whatever bonus, and I buy blueprints later at my own pace.
