"How do I redefine a CSS class in javascript"
You can create a new <style> element and append it to the head. This should probably be avoided if you can help it.
If you simply want to toggle between 2 states, consider putting both sets of rules in the CSS and toggling a class on the body or other container.
*"Should I use BOSH for XMPP on the iPhone?"
Probably not. If you have a long-running low latency XMPP connection, you'll probably want to use a socket from the CFNetwork package. That's the most we know about iPhone development right now.

- Web based sprite generator - here
This also makes the generated sprite really small which is great if you care about page load times. A Ruby+ImageMagick sprite generator might also be a good thing to build.

"Is there an onReady() for AJAX events?"
- onAJAXReady() ?
- JQuery Live Events might do the trick
- Our site has a number of buttons which are: (a) really links which look like buttons instead of links, (b) ajaxy actions, which typically cause an edit box to appear, or (c) form submissions. This item is especially about (a) and perhaps (b). Right now we have what is a glorified styled a tag, as described here. We've been having trouble getting that to work right (in particular, the height seems off by one pixel in mysterious circumstances). Probably the easiest solution is the rails button_to helper, which makes a form with one button in it (and method=get). This loses some desirable behaviors of the a tag (such as being able to control click or menu-click to open in a new tab), but certainly solves the rendering hassles.
There is a firebug that works with Firefox 3, it can be found at GetFirebug.com. The current beta version 1.1 appears to fix a problem that Firebug was having with inspecting anchor elements.
Also, there is a google code project ie7-js. It is a Javascript library that attempts to make IE7 behave more like a standards-compliant browser. It includes a limited PNG transparency fix. It also gives you Pseudo-element like :before and :after.
Combining this with yui and IE7 gets a lot closer to behaving as you might expect!
