Possible To Add External Site Link & Attendance Restriction?

I'd like to add fields to the Event Details area to show up with date/time, location, cost, etc. on my event page. I'd like to add a link to the location and/or sponsoring charity and notes on attendance restrictions/limitations. I also think it would be great to have a space there for parking information.

Is there an easy way to add this info to the plug-in so it just shows up on a new event with fields to fill in?

Also... is there a way to edit the layout of event_details?

Thank you so much!

P.S. I'm using WP 3.3.1 and the most recent Events+ plugin, 1.1. Also running the Google Maps and Membership plug-ins.
