I'd advise coming to join our discord, and chat in the new player channels, etc. In terms of what skills to train, UO is an open world sandbox, literally can do almost anything you want - so it helps to give some direction on what that is.
For you, as a ranger, you are looking at a template probably something like:
100 Archery, Tactics, Anatomy,
80 Resist, Healing, Tracking, Arms Lore
That leaves you 80 - 100 (100 after skill balls), to play with - a few options:
Camping - gives +dmg +backpack size
Taste ID - gives resistance to bleeds, poisons +swing speed
Forensics - gives +dmg +leather when skinning
Chivalry - down the road more so, but gives you some all around utility for dexxers.
