1- yes there is a few guilds around, for all gaming time.
2- race does not matter
3 - I would advise you to put your points into charisma , druid have mainly heals and nuke/dots. Your mana pool for heal depends on Wisdom and the more charisma you have , less chance to have your nukes being resisted by mobs.
Wisdom is pretty easy to raise with gear, also each class have 2 good quests for different levels. Starfall quest and Thurgadin quest. The first one can be done in your early 30 , the second one will be later, around 55 or 60 if this is your first character. Both gives good items for their levels so I would strongly advise you to do them.
Another good source of information is shard of Dalaya Wikipedia
http://wiki.shardsofdalaya.com/index.php/Main_Page
On the right at wiki homepage, you will see a character section with details about all classes you can play, that includes all the spells for casters, including druid of course and what they can do .
Druids can solo well and are very good for group since their heals are good, also when you will do treasure map later on, not only you will heal your group but also will port them all around .
