webOS skill level: Beginner
Technologies covered: HTML, CSS, Javascript
Prerequisite knowledge: Beginner-level HTML, CSS, and Javascript
This tutorial is for people who have had some experience with HTML, CSS and Javascript. You've put together a few sites, perhaps experimenting with CSS-based layouts. Well, great news...you already have a lot of the knowledge you need to build webOS applications!
Although the webOS SDK hasn't yet been released, Palm has provided all the information you need to brush up on your webOS development skills. On the Palm developer page, Palm states that the Mojo application framework is "based on the HTML5, CSS and JavaScript standards that web developers already know and love". By building our skills with these technologies now, we can get a jump start on Mojo the moment it's released.
HTML
You already understand the basics of HTML, so start with this tutorial:

Even developers who have been using CSS for a while will probably learn something new by stepping through these lessons.
Javascript
So you've written a few functions in Javascript and are ready to take it to the next level. Javascript is likely to be the meat-and-potatoes of webOS programming, so these will probably be the most important tutorials to go through:

Go through the JS Objects and JS Advanced lessons.
