What do I need to know/have before becoming active in a guild or with others?

I'm brand new to the game, and I'm starting to get the hang of things. It's becoming apparent that playing with others would be a good idea under certain circumstances, but I also don't wanna be the one ***** dragging the team down if I don't know what I'm doing. Most of the people I see are level 70+ meta players, and while I'm level 18 and can handle most all 1v1 encounters in the early game areas, even getting 2-3 enemies attacking at once can kill me. Walking into later game areas or a PvP zone results in instant death.

I'm an undead warlock, and my current battle strategy is to have Demon Skin and a summoned Imp always active, cast Curse of Agony and Immolate if I think the fight is going to take a minute (most don't), tell my Imp to spam Firebolt, and then spam Shadow Bolt until it dies. It's mostly effective, but is this optimal if I'm playing with others? I don't want to be using a spectacularly suboptimal or off-meta strategy and drag the team down.

I've just started learning enchanting. What other profession should I pair it with? I'm leaning towards tailoring or engineering, and I think engineering would be better, but I don't know.

My gear sucks. The Demon Skin spell absolutely helps, but I suppose I'll find better armor as I do quests and my enchanting levels up. There still seems to be a meta around gear that I don't understand. Is there anything I need to look for?

I've already been recruited by a guild that's been aggressively recruiting in the Undercity area, and there are players of all levels in it, but I assume most or some already know the game's ins and outs, and I don't want to be a burden on the team. Is there anything else I should know or do before I try to start or join a party?

I can't believe the word that got filtered got filtered. It makes it look like I said something much worse than I did

A guild that's willing to accept you, is willing to accept you. You don't need to worry about how to play the game, unless you join an end-game guild that's focusing on clearing max level raids on hardest difficulty like it's their meaning of life.

Learn the way you think is the best for you. Doesn't matter if it's by doing things yourself, watching a video, reading a guide, being taught in-game by more experienced player.
Only thing I recommend doing yourself is reading the rules of the game set by Warmane.
From https://forum.warmane.com/forumdisplay.php?f=3 I recommend reading "[Realm] Players Code of Conduct" and "Reporting Players." These topics gives you a good view of the rules and how to report rule breakers if you come across one.

No need to self censor. You can say **** and **** as you type, but if the censor catches it, let it do its work.

Thanks. Yeah. I just don't want to be a burden to my teammates. Apparently the guild in question is accepting absolutely everyone; I got an invite without the person who sent it even talking to me and I'm seeing my fellow guildmates EVERYWHERE at just about every level. I guess we're taking ove

The word I used was incredibly mild (and not even a swear word). I know that if I was reading my post, I'd mentally replace it with something much harsher when I was trying to decipher it.
