General Support: CSS Exclusion / Modification & Custom Integration

I'm looking to modify the URL variables that get passed along. Basically, a gallery requires me to plant itself some place in /gallery/ ... where as I want integration into ?mypage=gallery and then have the rest of the gallery variables passed along onto the URL.

I have to hack out the CSS because I have spent way to much time developing my own, but it's ok ... because that's one thing, but the URl is the other.

Any easy way of doing this? At least a section that you can ADD ON your own URL variables along with stuff that gets sent along for the gallery. That seems pretty simple. It allows for manipulation via. custom interface to whatever the wrapper may be for the gallery.

In my case I drop in a template page and put the standard header, footer, etc around it. Most devs. use three ways of passing around information or formatting it. URL, form, and session. If I can't manipulate the URl variables in some way, it seems retarded to say this integrates easily with just three lines of code. It REALLY doesn't ... because of the general flow of information between client and server.
