Re: ULTIBOARD ANY VERSION
You can go to Edit > Properties of the board > Board Settings and can set layer pairs to 1. This means you have Copper Top and Copper Bottom to route the signals. You can use Copper bottom.
As for the libraries, I guess you can do one of the following,
1. create the footprint for the new part using the Component Wizard
2. copy existing footprint from ultiboard master library to user library and edit it it to meet your requirements.
Hope this helps,
