Lauren,
You're off to a great start! Especially if you've never built a site before. If you can I'd clean up some of the text a bit and maybe change the title from "Welcome to my site" to something like "Welcome to Work from Home Online!" or something.
If by "linking my pages to the home page with specific words" you mean being able to click on a word or phrase on page one and have it go to page 2 (for example) you'll have to link that word or pharse. I'm no HTML master
