Small urgent fixes in oscommerce

I have a modified oscommerce script and i urgently need these 3 fixes. I know a few things about php but i am not an expert so i need help: 1) I have installed a custom product sort order module in admin but it does not work in user side (product listing). I tried but i am apparently doing something wrong. 2) I need each category in admin to have a green/red button to activate/deactivate, just like products. Red categories should still be accessible directly through http, so their url should be mentioned in admin panel so that admin could easily access deactivated categories. 3) There is a custom field for category intro image. I need another field named "category intro rollover image" so that user could see another image while he rollovers on that category intro image. i have the sts template module installed for template manipulation.
