I've played Guild Wars since it first released, and at one time I enjoyed the hell out of it. Don't get me wrong, I still love this game, I made a lot of friends over the years. People are right when they say that it's hard to find people to play with, especially if you're looking for someone to go through leveling with.
Several others mentioned learning to use the henchies and heroes... this is a great way to learn the game and it's mechanics, but don't forget to peruse all of the resources the internet has to offer. There are a ton of sites that pretty much walk you through the best way to complete every mission and quest in this game. Note, though, that some of these walkthroughs MIGHT be outdated, as sometimes with some updates to the game, things get "nerfed" (certain character and group builds or skills change in a way that make the original idea of the build or skill not quite as usable, or worse, completely worthless).
And stick with Prophecies as your first experience of this game, it is the easiest to pick up. It's a great stepping stone to the other two. Factions will be the most challenging of these, and will require some grouping at some points. Nightfall is just about in the middle as far as difficulty. It also has the best storyline (in my opinion).
I'm not sure I would have gone with an Elementalist/Monk for your first character. But honestly, this is a matter of personal preference. And someone else frowned on this, but if you learn to use the right build (skill bar, armor set, etc...) you CAN finish Prophecies with an E/M. I would have chosen a Warrior/Monk as your first character if I were you. Warriors can take more damage, and a newcomer really needs that extra protection. Not to mention, warriors have running skills... they can help you get through some areas or out of tight spots.
Gold/Platinum - I guess by now you've figured out that 1000 gold = 1 plat. Save your gold Sean, don't waste it on dyes and crap until you've got a nice amount saved and an armor set you're happy with. I'm surprised I'll be the first to mention this, but armor in this game get's expensive. And some dyes are ridiculous because so many people buy them (i.e.. black dye is popular, so the price goes up). Buy yourself a salvage kit, identification kit, and collect materials. You can make a lot of gold collecting and selling something as simple as wood. This is assuming you never try to sell anything to other players and just rely purely on your own collecting and selling to merchants. Making enough gold and collecting enough materials to also buy your next set of armor can be a pain.. thats why I say save your gold and not waste it on dyes and junk until you've gotten far enough along.
Runners - you will inevitably run across people announcing something like "running to Piken Square, 500 gold" (or something like that). Most of these runs are legit, but stay away from the ones who ask for full payment up front. The usual way is to pay "half now, the rest at the destination". But let me make a suggestion... don't "run" anywhere. Be patient and play the game. Most creatures you fight along the way don't respawn once you've killed them (there are a few that do, mostly boss-types). So you can clear an area a little at a time by using the respawn points throughout the map (those places your character respawns after you get killed).
Most players have become very bored with GW Sean. And, to get a laugh or a rise out of someone, they will team up with new players, get them part way through a quest, then bail or just aggro as much as possible. You can't avoid this, just know that it does happen, take it in stride. There just isn't much you can do about it but find someone else or make a henchie group and try again.
It's a shame you didn't decide to try Guild Wars back when Prophecies first came out. It used to be so much fun joining a guild, teaming up with your new friends and doing quests and missions all night. I spent a many a night laughing my ass off in front of this screen. And we've all replied to this post and pretty much talked down the idea of teaming with others. Fact is, there really aren't many lower levels in the game who legitimately WANT to play through it, but they are out there. Like someone else said, check the guild recruiting forums here.
Finally, learn to walk first. Stick with PVE for now. Get very used to using skills, moving your character, etc... because, PVP is quite difficult if you don't know what you're doing. In PVP, moving your character is just as important as knowing what skills to bring, how to use them, when to use them, and where you're supposed to be.
PM me for my in-game character name... if we're on at the same time, I'll hook up with ya and help out. I do have a few low level characters, I think I have a level 11 in Prophecies actually. If you make a warrior, I may even have some very nice weapons to give you. Good luck, and sorry this is so long!
