Buddypress - changing buttons colours

Hi support,

I have just installed Buddypress on Woo themes Canvas, all looks ok, apart from the buddypress buttons themselves, they're overriding the theme's button colour of to a very light silver, I wouldn't mind, but it's near impossible to read.

I've tried to inspect the elements with firebug but can't see the necessary css code to add to my custom.css file.

Can anyone help? You can see the buttons here: http://www.townflo.co.uk/activity

PS. Buddypress is also taking up the whole page on this theme and pushing the sidebars down underneath the activity stream, anyway to constrict the buddypress column width?
