To answer your original question, Vbrandon, the 18-55 kit lens and a 55-200 telephoto will do you very nicely for almost every situation. Talking about "crisper images" that you wanted, a DSLR will certainly help with that. A crop DSLR's sensor is about 7 times larger than a high-zoom point & shoot camera, and the general rule is that the more pixels you cram into a space, the more each pixel quality will degrade.
And with regards to the tripod, that one will do you. I use a £20 Jessops tripod, and it hasn't fallen over... yet. Sure, I need to allow for its lack of rigidity, but it works. So long as you keep an eye on it and set it up carefully, your camera will be fairly safe (I say "fairly" because no matter what support you use, having a camera suspended 1.5m off the ground isn't exactly safe as houses). Also, a proper tripod will certainly minimize camera shake, but yet again, it is possible to compensate for this with a cheaper tripod.
For example, The bunny photos in
this thread were taken at a very slow shutter speed (average of 1/20s), at 200mm, and with no mirror lock-up for self-timer mode. And they came out OK, right? RIGHT??
The bottom line is that a "bad" tripod will do you, you just need to be careful.
