This is a tough game to get into as a total newcomer.
I had never played EQ before P99, started with absolutely nothing save a few cheap things one of my RL buddies that convinced me to play gave me.
Definitely browse the wiki extensively before you roll a character and start playing. I've been playing here for years and I still keep a wiki page open while I play.

Some of the guides are a little outdated, but still relevant for a 100% beginner.
I recommend a class that performs well in groups with very little money and are easy to play: magician, necro, cleric, druid, shaman, rogue.
For your first char, I'd stay away from enchanter, warrior, bard, and wizard (unless of course you read about the class and are 100% certain that's what you want).
This game is amazing, it just takes time and patience to really appreciate it. You don't really get a feel for your class / kit until somewhere around level 29 or 34. For you, this could potentially be months down the road depending on playtime and how much you use the in game players / wiki / forums for information.
Keep us posted here on what classes / playstyle you're leaning towards and we can help guide you from there.
Once you take the leap and hit "enter world," hit me up and I can get you started w/ some bags, a bit of plat, and some super cheap gear.
