MarketPress Options

We are using MarketPress with Authorize.net as our payment gateway. I would like to add to options/features and do not know if there is a plugin or method to do so.

1. Add a donation field that would allow the user to enter any amount of donation in a field for a given scholarship fund and "purchase" it.

2. Have MarketPress send an email to our office manager with all the field information for a product purchased including which product was purchased. Currently the only notifications sent are to the purchaser and from authorize.net (which does not include the product). In order to see which product was purchased, we currently have to log into MarketPress and review orders individually.

Any ideas?
