php & mySql adjustments to existing site

I have some changes to an existing web site that I need fixed. These include: 1) Make the scroll bar longer (or the viewing area larger) for viewing the main screen where members enter after entering their id and password. 2) Make the viewing area larger for viewing info, etc. 3) Create ability for certain members to login separately from other members and view only the following information: Member ID, Member Name, Member Address, and Phone. These need to view a list of current members. Is it possible to have ability to export list of members with these fields only, to comma delimited file? 4) Add ability to choose category (and create new category) on supplier registration page, so we don't have to labor thru classifying each supplier that joins. 5) In Admin Area, sort suppliers by name, and provide some sort of way of either searching for a specific supplier to edit (like the pull down menu maybe). 6) In the Write a Review Area - Add instructions: "Please be professional in your comments. Some comments may be blindly forwarded to suppliers to show them what they are doing well, and where they could improve." 7) Incorporate design of new site into old site.
