Fetching as Google works, as already suggested. However stage 2 should be - submit your sites to several large social bookmarking sites like digg, reddit, stumbleupon, etc etc. There are huge lists of these sites out there.
Google notices everything on these sites and it will speed up the re crawling process. You can keep track of when Google last cached your site (There is a big difference between crawling and caching) by going to.. cache:sitename.com
