Joomla Site Mods and template changes

Joomla site template change and add-on scripts install: 1. The current Joomla template (called Vintage -- [login to view URL] ) has a dark brown background, and a lighter tan/parchment colored contents blocks. However when in the ADMIN section the text / content entry window comes up in the dark brown color, making it exceedingly difficult to SEE the text/content you are entering. Need this window to be the standard black print on a white background for data entry purposes. 2. The person that installed this template for me turned on some control called CRON jobs and this is apparently still turned on or something is not working, because it is also causing hundreds of CRON job error messages to come to my email address allerting me that it is unavailable or not permitted or something. I need this turned off or fixed. I can supply the old messages to give some background info. 3. I need to have the VirtueMart eCommerce function updated (it is installed already) to accommodate my 4 or 5 info products (which are snail mailed to buyers). Remove the junk products out there. Allow me to accept payment thru Paypal for the items, capture their Name/Address info, and send me an alert email with this order info...so I can prepare their package and verify their payment. Also they should be able to print an invoice and mail me a check as another option. 4. I need to have either OpenGroupware or eGroupware script installed under a Support menu function choice called " Project Wizard"...which would actually be installed on its own domain called ProjectWizard.com...as a free standing function. 5. I had the "hesk" suport ticket system installed and I need it attached to the menu,under Support -- Help Desk menu option. 6. Place the rest of our content block text out there, now that we have these sections written up. Add a few new sub-menu selections/topics per the existing top menu bar's categories.
