It's a good price, cheaper than leisurepro, and it's tough to find SP equipment at a discount with the warranty. If this is a package, I assume there's some sort of SPG with it; either the computer is in a console, or (better IMO) a wrist mount with a separate SPG?
Probably you'll love the regulator and be happy with the computer, although you should do a little research to determine if you want a more conservative computer. The big question is the BC; they're pretty personal and there are huge differences in the way different styles feel in the water. Best bet is to try a jacket style, a back inflate, and a backplate/wing set up before you buy anything. If you really can't do that, you could search threads for this BC; I'm pretty sure you'll find favorable reviews. But...you might also resign yourself to the fact that it's likely at some point down the road you'll want to try a different style BC. If you did a poll among divers with some experience, I bet almost every one of them will have owned a couple of different types of BCs, especially on this board where there are so many rabid BP/wing zealots. (Sorry guys, I'm sort of one myself...) It's not the end of the world, you're getting a good deal on the package, and after a couple of years' diving, you could end up selling the BC to pay for your BP/wing rig, and not lose much money in the process. OTOH, you might love diving in it for many years. There's not much of a way to know without several dives to get used to it. While getting in the pool with it is a great start, you won't have the real awareness of trim and fine buoyancy control until lots of dives.
I'm a professional guitarist, and I run into this sort of thing with guitars all the time, especially with my students. You really don't know what exactly you want until you play it for some time, far longer than the typical "try" period. So, if the deal seems okay and you want to learn more, you buy it, learn with it, and later on, you pass it on when you have the personal experience to know more exactly what you're looking for.
