Those builds all seem pretty good! The thing I like the most about Rangers is that there really isn't a single "best" build. The gear you should have (or try to get) and the stat/skill layout depends a lot on how you want to play, what gear/skills you already have, and whether you are willing to spend gold on consumables.
A skill like Light Heal, for example, is excellent for Rangers that don't want to spend gold on consumables like restoration potions.
Camouflage is pretty good if you don't have many resurrection idols, and need to travel longer distances safely.
Double shot is great if you have higher strength and/or weapon damage, since it does twice your normal auto attack damage.
Sharp Shot and Longshot both get stronger if you have more dexterity.
Rapid Shot is a nice skill to put extra points in, though it's most beneficial if you have higher auto attack damage.
Steady Aim and Sharpen Weapons both are boosted by more dexterity, and increase your damage (and attack, in Steady Aim's case). Those are pretty good for a more even str/dex build, and I'd recommend steady aim over sharpen weapons, due to a higher buff.
Stat-wise, 2 Str/Dex and 1 Vit is a good starting place. As you get to a higher level and get better gear, you can change it up. Starting off, you will want points in Focus, especially if you don't have energy regeneration gear - but as you get to be a higher level, your gear might add energy, so you may not need the Focus.
Strength and Dex work well either way.
Usually, a Strength-focused build works best with skills like Double Shot, Rapid Shot, Longshot, and Steady Aim. For gear, you would probably want skill rings that boost those skills, but as you get closer to endgame you will probably want gear that boosts your stats and damage.
Dexterity builds usually rely on skills for their main punch, and usually include Sharp Shot, Longshot and Steady Aim. For gear, items that add skill points are definitely wonderful, as well as possibly some gear that adds direct damage to your skills if you can find it.
Light Heal is always helpful, especially if you are a more casual player who finds it hard to save gold for consumables. Steady Aim also (I mentioned it for both Str and Dex characters) since it adds a decent amount of damage and attack to your hits, lasts a fairly long time, and is nice and fast to cast.
Hope some of this info is helpful!
