how to "help" google rescan a page?

hi guys,
i had some site on my domain, then i changed it. The thing is that after the change, all my new pages were indexed fast (rss + ping), however my homepage did not changed - it's still show old title\description on search.

The problem is that after 2 weeks i got this site to first place (1200 searchs\month) but i don't get any clicks b\c the wrong title.

i tried Rss time after time, i tried links and ping - still nothing.
in this time all other pages indexed, but once again - the homepage is the same.

how can i "help" google to understand that i changed my homepage? can i do something that i havn't done already?

thanks !

Are you using wp? And any seo plugin? Check that the general settings and the seo plugin have the same title information

that is kind of weird, surprising...no, but..
do you have your site in googles webmasters?
have you submitted a sitemap?

no, it's self made system, not WP.

i have sitemap on site, no XML. don't have WT on this domain. adding sitemap to WT never helped me to get index faster so i besiclly stoped adding things there. install it only for see links and searches.

anyone have some idea? i'm besiclly loosing money every day, so will try everything.

my longtails brings me users, and my main keyword = 0 users.

thanks
