What would the specific wget command be to download all files, say ending in .zip, from a certain directory on a website? It would be an HTTP download, not FTP, and is there anyway that I can set a gap between the downloads so I don't completely hammer the website? It would just be inconvenient having to sit and click every "Download" button, when this could be much easier and I could do it over a much length period of time. Also, I'm assuming it would recognize wget as a bot of some sort, and potentially say, "Haha, no you can't download", is there a way to trick the website into thinking I'm your average run-of-the-mill browser?

Download recursively, specify a file pattern, and specify a wait time, like this:

wget -r -A "*.zip" -w 30 http://www.foobar.com/foo/bar.html

assuming the zip files are pointed to by links on the bar.html page.

If the links are to different subdomains, you can specify host-spanning using the -H option, e.g. if bar.html contains links to files on host src.foobar.com, it won't fetch them unless you specify -H. It's also a good idea in that case to limit spanning to a domain using -D foobar.com.

The -w option waits 30 seconds between retrievals, I think.

You can also use --limit-rate=20k to limit the download speed to 20kb per second.

To "trick" a web server into thinking you are using another browser, you can use the --user-agent="User Agent String" option. wget man page says this is discouraged, though.
