Welcome to RoM,
To be honest, quests will get you pretty far. You can sit down and level to 30ish in an hour without having trouble. While having a group low level to quest, you really don't need to have a party. If you do need more information on the game, I can suggest a few websites to do some research. You could also look for a guild, there is bound to be one that is willing to help you.
Good Luck!
