Q:
Need help with a mesmer build
A:

And I’m not trying to be a kitten with that -- there are some good discussions in the profession-specific sub forums, and the mesmers posting actively there will probably be able to help you.
For example, there’s a nice sticky with some of the builds and guides available:

Since you are only level 25, there is a lot that remains unavailable to you until you gain more levels and unlock more of your traits and skills, as well as your elite slot at 30.
edit: Also keep in mind that as an up-scaled player in WvW you will be a much easier target. Don’t let it get you down -- there’s some good fun and good leveling to be had in wub-wub.
As you mentioned roaming and flipping camps, you might want to do as Sitkaz suggests and invest in Chaos traits -- with Chaos you can boost your staff skills as well as your toughness and boons. A staff with, say, scepter and focus might be up your alley (or sword, in fact, instead). The staff and scepter will help you lay down conditions/confusion, and the /focus gives you our only mobility spell (sword is some nice close damage, too, if that’s more appealing).
I would highly recommend looking at Illusions regardless of weapon choice to maximize confusion and shatters, as well.
You’ll also want to look into Dueling if you want to pop out clones whenever you dodge.
For utilities, I like Feedback, Null Field, and Decoy for starters, if they seem like they’d fit into how you want to play. In my opinion, our utilities are a lot of fun regardless, so explore them all when you can as you earn skill points and unlock them.
These are just thoughts, though. I suspect the build threads in the mesmer section will be of more help than me.
I use staff and put a lot into the chaos line. I have good survivability and can make a lot of clones quickly. If you’re looking to annoy people, zipping around with 3 copies does the trick. Damage isn’t super high with staff though.
My mesmer didn’t really come into her own until about level 30-40 so don’t be surprised if your playstyle changes a lot as you level.
what should i use for my utility skills?
