Welcome to the forums! I am no long-timer or anything but if you need anything, we will try to help ya out.
As for your druid. He honestly has a bad start at becoming super strong, but if you stay in nightmare or normal games, you will still have alot of fun. If you can, try to focus on one skill tree (summoning or elemental) from here out to become as powerful as you can. Some good items to shoot for are: Jalals helm, Skin of Vipermagi armor, any plus to skill amulets, or any summoning or elemental charms.
For stats, try to get as many points as possible in vitality, enough strength to wear your gear at the time, not much in energy if any. Depending on whether you want to use a shield or not, points in dexterity. If you want to use a shield (for blocking), you will want points in dexterity to increase your blocking. Otherwise, dexterity points are not as efficient as vitality, in my opinion.
