if its bad just give me some suggestions, im kind of a noob to this monk thing so if thats what you call me i understand

Its a good start. A basic all-Monk boon prot build would, first of all, have Divine Boon in it

Try this, it's very basic but it is also not too complicated so it will be easy to get used to...

Divine Favor - 16 (12+1+3 from head tatoo and sup rune)
Protection - 13 (12+1 from minor rune)

1. Reversal of Fortune
2. Guardian
3. Mend Condition
4. Prot. Spirit
5. Aegis
6. Divine Spirit
7. Divine Boon
8. Rebirth

- I left off the elite skill since I don't know if you have one yet.
- I left off Factions skills since I don't know if you have the expansion.
- Keep Divine Boon on you at all times. If it gets disenchanted, cast it again immediately.
- Mend Condition is more useful than the now nerfed Mend Ailment most of the time. It's also good to get into the habit of not being in the line of fire. Lacking the ability to cure conditions on yourself should help you learn this pretty quickly.
- Divine Spirit, learn to love it as much as possible.
- Rebirth instead of a Res Sig. Only use it when out of combat. You should be protecting while in combat, not resurrecting the dead

Give this a try and see what you think. As I said, this is very basic and meant to limit the number of variables you need to focus on until you get the hang of monking in general.

If he's new to monking I'd stay away from boon prot, since it's quite difficult to micromanage everything. First of all if you're going to be playing a protection build you don't want a superior divine rune (unless you plan to boon prot, in which case you don't want sup prot.) Running 2 sups is dangerous, as you have 150 less hp, for a marginal gain. As a prot monk your job is to reduce the ammount of damage done so the healer doesn't have to do as much work. It's basically 'indirect healing', a term that I just made up, and seems to fit the situation quite nicely.

As a prot monk, there are a few things you will usually want in PvE:

Protective Spirit: massively lowers the damage of elementalists and other spiking opponents.

Reversal of fortune: great spammable damage reduction and minor healing

mend condition / mend ailment: depending on where you are and what you're doing, one of these is usually necessary. In areas with lots of conditions, use mend condition, since it's very spammable.

Aegis: great against all forms of attacks (warriors, assassins, rangers) and will stop 50% of their damage.

Holy Veil: works just like remove hex, but it's a faster cast. Simply cast it on an ally and remove immediately for a quick hex removal.

Hard res: In PvE (NOT PVP) it's generally assumed that monks will bring a hard res, generally rebirth. Never use rebirth during a fight, only after the battle has ended.

Until you have some useful elites, I'd say your build is fairly good to start out on. I'd change just a couple things for now, and then as you get used to it try other skills:

a: drop res sig for rebirth (definitely)
b: get rid of the superior divine, and make sure you have a protection scalp
c: try switching out remove hex for holy veil
d: try to work in some energy management, possibly from the inspiration magic mesmer attribute (inspired hex is a common choice)
