just make sure your carrier is the right series, i believe it is 2 or 3 series
those gears should be for a 3 series i believe
texas speed should be able to help you out with a positive answer

You need a thick gear set for a series 2 carrier. You might better call Jon at TSP and make sure thats what you are getting because if not you will have to buy a series 3 carrier to make it work. Jegs sells a thick gear that is made to work with your series 2 carrier. It will also last longer because the gears are stronger.

I ordered a modified eaton lsd (3 series) to use. I read up on it before I bought it. it was 610 dollars and build to handle 475hp. from what I read it would be strong enough to stand up to the beating I will put on it.

That kit looks like pretty much everything you'll need.
Do you plan on doing it yourself? If so, I'd recommend some loctite & RTV.

I think you're making the right decision by taking it to a shop, but it would be the same amount of work whether you're just swapping gears or replacing a differential too. The ring bolts to the differential, so you'd have to take it out anyway. However, the job is a huge pain in the ass if you've never done it before, and a couple specialized tools are needed. Just make sure the place you take it to specializes in drivetrains/rear ends. It's pretty precise work, so there's something to be said about getting a quality job done.
Out of curiosity, I looked up the Ratech install kit they include. Here's a part list: pinion shims, carrier shims, crush sleeve, pinion seal, pinion nut, ring gear bolts, cover gasket, and pinion, carrier bearings.
