Is this a good deal?

This will be my first SLR camera. I am very much into photography but right now I make the best out of my point and shoot camera. I do know the basics about f stops, ISO, exposure; I am no expert, but I am a good learner and I do plan to get better. I will be using this camera mainly to take wakeboarding pictures and to take pictures of my jewelry (which I make).

So my question is, is this a good deal for that price? Will those lenses be enough (for now) for what I want to use the camera? I need a good Macro for my jewelry, so that's important too.

The other lens that comes in the kit (Canon EF-S 18-55mm IS Lens) is it good or should I just get another better lens separately?

Thank you ;)
