I assume this means you already have a computer that is decent enough to handle audio recording. If so, then the Mackie and the Gina card are decent starts.
Depending on what you plan to record, you might want to rethink the Shure SM57/58 mics. If you plan on doing any vocals or acoustic instruments, you'll probably want at least one condenser mic in your arsenal. The SM57's are best suited for amplified instruments or drums. Most studio's will have a few of them in their mic locker, but I don't think that you want them to be your ONLY choice.
Sonic Foundry is a company, I believe, not a program and I'm not familiar with Vegas Video. I think you'll find more people using Sonar, Cubase, N-Track, or Nuendo as their multi-tracking program.
I'm also not familiar with Zoom CD recorder. If it is a standalone unit, I suggest you might want to think about just getting a CD burner for your computer. It should save you some money over a standalone unit and would allow you to keep all your music, once recorded, directly on the computer.
Also, I don't know that you need a compressor (although the RNC is well regarded for the price). You can use software compression. Again, much depends on what you plan to record.
You may at some point also want some plug-ins for your recording software - although programs like Sonar come with a decent starting set that will allow you to get started. Later on you may find yourself looking for a better sounding reverb, or better dynamic processing plug-ins.
That's the problem with this hobby. You never run out of things you can buy. As someone once told me when I was considering getting into this,
"STOP!! TURN BACK!! IT'S NOT TOO LATE!!"
