Alterations to Wordpress

Project Description:
1, The default image displayed as the categories thumb is currently the lowest numbered image in the database for that category. In order to change the image for the category I currently have to manually edit the database and change the image_id in the wp_slider_images table. I would like to have an option in the /wp-admin/admin.php?page=product-management_category page to select which image I want as the category’s thumb. Another way of doing this would instead be to have the image_id field displayed within the “Edit Product” box so that it can be edited easier. I would prefer the first option.

2, In the http://www.chrisbellphotogallery.com/wp-admin/admin.php?page=product-management_manage screen, it would be helpful to have a selection so as to filter the images in the list. The list is rather long already and will only get bigger. Please could I have added:
A, A search box for an image name
B, To be able to select a category and only display those images

3, The description box in the “Edit Product” page to be made larger by default. I know I can manually enlarge it by dragging the corner but the default is too small, enlarge to at least double its current default size please.

4, When we look at the site using Firefox or Explorer, everything is displayed correctly. When we look at the site using Safari or Google Chrome the site title, “Chris Bell Photo Gallery” seems to be 4-5 times larger than in FF or IE. Could this be looked at and solved?

5, When viewing each category, could we please have the category name displayed at the top as a H1 and centred. At the top of the /product-gallery page where all the images are displayed, this is to just say “All Galleries” as the H1 title. To be displayed just as the image title is displayed here /product-details-page/?slider_category_id=1&id=105
