A Better Browser/config Or Faster Wifi?

I have a work related website I'd really like to access with my z. For starters I will say this site can take minutes on a regular laptop at g speeds. I have a CF-b card. Opera 7 does not appear to fully load the pages properly(drop down menus aren't functional on the page). Firefox does, but it takes an hour to get anything done. I've requested that the company send me the list of services the browser must support for full operation. Has anyone thought of updating Opera to version 8 or 9? I'm not sure if these versions have all the features I need yet, but 7 is not hitting the mark. I'm considering moving to an X based rom from Cacko. But firefox seems to be slow no matter where it is. My other delimma is I need video playback(xvid/mp3) - and cacko does that so well (no overclocking ).

Any advice how to configure this beast for the features I need would be greatly appreciated. I hope to have more details in a few days.
