Hello! I've seen a few "help, I'm underleveled!" threads cropping up already, so I'll start by advising you to go to the starter island. Each alliance has a different one (Khenarti's Roost in AD, Stros M'Kai -> Betnikh in DC and Bleakrock -> Bal Foyen in EP). There should be an NPC ready to take you there around the area where you woke up.

Check out MissBizz's guides, I think there's a link to Craz's written guide somewhere in there too.

Basically, go out, do quests and have fun. You might be able to make money off crafting (mostly selling mats, but also sets for new players) soon if transfer players don't corner the market, so it's worth investing in even if not just for your personal gain. By clothing I assume you mean armor (there's also actual clothing you can steal and disguises from quests, crown store etc.) Don't ever buy it from merchants (unless it's a PvP set), they're prohibitely expensive. Instead, simply gather all materials you can find. This will be difficult now, though, because of thousands of player doing the same thing in low level zones. Crafting experience, called inspiration, is best gained through deconstructing stuff. You may notice that many items you loot have traits (weighted, precise, reinforced and so on). You can research them at the appropriate crafting station, I recommend starting right away because it takes a lot of time. Researching allows you to craft special armor sets.

Just do the quests. Use the gear you find, vendor the rest, you will make 20K to 30k gold from the first zone.
