With regards to useful Javascript tools, something I find really useful is AjaxRecentChanges. It automatically refreshes the recent changes every set time period (mine is set to 15 seconds), meaning you don't have to constantly hit "refresh" to see new changes. You can also specify your own pages to refresh, which has helped me out a couple of times in the past.

LastEdited is a great tool for quickly spotting vandalism/bad edits, as it adds a small section to the top of each page detailing who last edited it and allowing you to view the changes they made without ever having to open the page history.
