You can download for free FileZilla (FTP) and TextWrangler (text editing).

If you know Unix/Linux command line, the Terminal app on your Mac will give you a familiar bash shell.

For serious web development you might consider a virtualization app (VMWare Fusion or Parallels) to run Internet Explorer (or even several versions of it) on the Mac. Or else set up your PC to share its screen and use Remote Desktop Connection for Mac. (The third option is running over to the PC to test IE, which is a drag after a while.)

There is also an Apache web server on your Mac. Check out Personal Web sharing.
