I'm new to this so bear with me please

If anyone would be so kind as to answer some questions I would be most appreciative. I'll even give you a /hug
Work Orders:
I was told batches are best. You skill up faster, get more xp, and get better coin plus an item which may be a rare. So that's what I've been doing.
Does the level of difficulty have any effect on how much xp I earn? On how much I skill up? On how much coin I earn?
Does the quality of the items I turn in have any effect on how much xp I earn? On how much I skill up? On how much coin I earn?
Items:
I haven't made any items yet. I've just been doing work orders trying to get to lvl 8 asap (so I can make bags).
Do I use the same tables to make items? I assume the recipe will tell me I'm at the correct table, right? I've only looked at some recipes and always see "You do not have all the items necessary...." I'm assuming those items are things I need to make but I want to be sure I'm at the right area. I don't expect a walk through
Thanks for your help if you are so inclined!
