I want to use a CMS and I'd rather not have to design one from the ground up. I like wordpress from what I've seen. The thing is, I'll still definitely want to execute my own code. I know there are plugins do to this.
1) How much overhead would they cause? Do you have specific recommendations for which to use?
2) How would something like php code affect plugins like WP super cache? Would it cache the results or..? Is there any way to control if it caches them or not?
3) Custom pages wouldn't be too big of an issue... site.com/mycustompage would work fine as far as I can tell. the issue comes with things like pagination. Would wordpress think site.com/mycustompage?page=2 is a different page entirely? Is there any way to control something like that?
Any general tips/warnings for someone that wants to use wordpress in this way?
