Hi Nicki,

to
Unfortunately, the earlier 3.8 V6 models had issues with headgasket failure, as you experienced. On a good note, it's not an indication of abuse by the previous owner, but on a bad note, it could happen again someday. Best I can recommend is to treat it fair, and it should return the favor. Don't feel bad about not knowing much, it'll come with time and we all had to start somewhere. In the meanwhile that's what we're here for.
Not really sure who you could have do the top, since I'm in IL, but I took the liberty of checking your IP address (have that privilege as staff) and discovered that you're near Albuquerque, NM. I did a quick Google search for some auto upholstery shops in the Albuquerque area, and came across this site, which could start you off in the right direction:
