Welcome.
I totally understand what you're feeling right now, it's awesome. My memory was fuzzy at first too, but soon enough I fell into old habits I thought were long forgotten.
As for advice, you should tell us what character you're playing. I personally think the Field of Bone is the best newbie zone, but that doesn't help you much if you're not an Iksar.
I recommend you make use of the
wiki, it's very helpful.
