Ok I'll try to answer your questions the best I can, although I quit EQ a year ago
1. When I played, the Tutorial wasn't actaully part of the online game, it was a little demo type thing to help you learn how to do things
2. Bard was my FAVORITE class, Too many awesome things about them, They can find parties pretty easy after 20 (First Mana Regen Song), also they can lull monsters at camps making it easier to pull them single, also they can mesmerize adds, also they can buff the party with different buffs such as HASTE or STATS or HP Regen and many many more.
2.(Cont.) As for solo, Bard was one of the best solo classes there was when I played, but not until the 40s once you had a few Distant DoT songs, and it got even easier at 49 (With 2.5 min Selos song) (Selo is very fast speed incerasment, well it gets faster as you level up and depending on your DRUM)
I would just run around with Lv 49 Selos on and use DoT songs on emenies, I wouldn't be the fastest killer, BUT, I would NEVER have to rest due to the fact that I NEVER got hit (Sicne I'm so quick) (You also get a Selos song at level 5, but only lasts like 18 seconds, but is obvioulsy easy to recast, and MOST songs don't use MP)
Ther was another way I would solo ONCE in a while, called Charm Kiting I believe.. you get a buncha monsters (Not sure excatly what kind, if they are on a faction or not), charm one, send it at the group of monsters following you (As you run with selos) and they will all turn and beat the crap outta your charmed monster, when the monster is nearing death, quickly use the INVISIBLE song and the monster will be uncharmed, you then throw one or two DoT songs on it, and hes dead - I've heard this is one of the quickest ways to earn EXP, but the higher level charm songs do require small amounts of MANA
3. The server(s) I played on were
Tarew Marr
Sullon Zek (Diety Alliance PvP)
My personal favorite is the PvP one, although now its not too populated since alot of players are uber and have very powerful equipement and can knock out a newbie characther in a single blow
If your not into PVP, I would suggest one of the more populated servers, I'm not too sure on which that would be since I quit along time ago
4. I never had a hard time finding a GUILD to be in, when ever I was guildless (which wasn't too often) I would be in a new guild later that day or the next day, since alot of my friends would want me in the guilsd they are in, all the servers have differnet guilds on them so I can't erally suggest a guild w/o suggesting a server.
Most guilds ARE friendly and will help you out with lots of things, when I needed help witha quest I usually had someone else who wanted to do the quest with me. I sometimes would have Guild parties where it would just be a EXP Party from the guild, those were usually the best for me.
Enjoy
