Crafted items can have a HQ version. The non-HQ version is like a much lower item level than shown, but it's usually still better than whatever you had previously. The non-HQ version is usually sold by vendors and the HQ versions are sold on the market board or provided by main story quests.

It doesn't matter what class you are. The classes are balanced and anyone discussing otherwise is talking about small differences at level 80 that don't affect being able to beat content in most parties.

Some classes might be easier to play than others, bard is easy at your level and you can switch later if it becomes too much.
