Is this a trick question or are you trying to build a wheel or just replace some spokes?

no, i just want to put a new hub in so that i can put in new disk brakes. is it possible or do i have to by it together(rim,spokes, hub)?

It's possible but if you don't have any wheelbuilding experience, I wouldn't advise it. Take the parts to a shop and have them lace it all up for you. It's not rocket science to build a wheel but it's also not for the feint of heart or those who lack patience. Personally speaking, it's an art that I would rather trust to the masters than have to deal with myself.

trying to build a wheel?
you first need the tools... truing stand, spoke wrench(es).
Next, you have to calculate the spoke length.. variables in w/c are, hub flange dia., no of crosses and lacing design, rim diameter, distance from center to flange, no. of holes/spokes, etc. You can get this thru the manufacturers or measuring it yourself.
When done, get the correct length spokes and start lacing... go to http://www.sheldonbrown.com for detailed instructions.
Then true the wheel. Redish if necessary then retrue.

Frankly, it's usually cheaper for me to buy a complete wheel already assembled than it is to buy a hub, rim and spokes to lace up myself.

Loosen all the spokes in your old wheel by going around the wheel repeatedly while loosening each spoke one turn at a time until all spoke tension is relieved.
Set your wheel on a workbench & align your new wheel / hub / whatever with it's replacement, move the spokes from old to new one at a time paying attention to location.
After re-assembly, I use my bike frame with a compass (the kind for drawing circles) zip tied to it as a truing stand. I had no experience when starting out (who does?), but I've rebuilt quite a few sets of wheels this way with excellent results.

After several years of building wheels to my liking, I find that to be true. The only thing I would do is re-tension all the spokes on pre-built wheels just to be sure.

That method works if you are replacing a rim with an identical rim, but I don't see how it's going to work replacing a hub. He's likely to run into some other issues too. Lots of newer bikes, the kind that have caliper mounts on the forks, have radially spoked front wheels. He's going to have to respoke that as a crossed wheel to work with a disc brake so the pattern will change and the spoke lengths will all be different.

I was trying to add to, without being redundant of, the excellent advice dexmax had already given covering these issues. It appeared to me that Emblem was following the thread farily well and should already be aware of the things you reiterate.

If you take your time, wheelbuilding using Sheldon Brown's article is fairly straightforward.
Detailed instructions are available here
http://sheldonbrown.com/wheelbuild.html
and also in French, German and Russian.
Since you have a new hub, you will need to find the correct length for the spokes, and Damon Rinard's spoke calculator (link on the above page) is easy to use. Alternatively, you may ask your LBS to calculate the proper length, but one shop I consulted was clueless on the subject -- IOW, don't always count on it!
A truing stand helps, but you could do a decent job by installing the wheel on the bike, lifting wheels off the floor (via bike stand, double legged kickstand or upside down), and using a pencil, then brake pads as gauge. I have built 3 wheels that way; 2 are perfect and the other has 2 mm side play (they are 1.5 and 0,75 year old respectively, with lots of loaded mileage on potholes). Still, I have two wheels to do soon and I might get a truing stand before.

one of the most important tools I forgot to mention....
