Hi Keith,
I'm relatively new to this too, so not a lot to offer you experience-wise, but I wanted to chime in on the SubQs as another person that does them at home. I was a smidge nervous at first, but it really is no big deal once you get used to it! I can' find the link right now, but on one of these sites I read a really nice story about someone with a needle phobia who passed out the first time she saw it done at the vets, but eventually was a pro at doing them at home too.
About equipment: It really is not a lot, and is easy to get ahold of yourself. When/if you get to a point that you're comfortable doing them at home, ask your vet if s/he will write an outside prescription for fluids and needles (if your state requires it), and then check out this site:

Basically, you can get several months worth of supplies (1 box needles + 12 admin sets + 1 case i.e. 12 bags of fluid) all at one time for $60-$70 dollars, and you're set. That's really all you need, and if you do it that way it's WAY cheaper than getting supplies from the vet and you don't have to keep making trips.
Re: the discussion about administering them solo: I'm another person who does this totally by myself, w/o problems w/ either getting everything set up or the cat. Honestly, even if I had a second person around to help I don't think I'd use them. Spike's a really cooperative cat in general though.
Best of luck and good vibes for you and Jasmine.
