Joomla Templates

Hi - I am getting ready to purchase the Trans Bear template to use for our church website. Only thing is - I am new to Joomla and don't know html at all. But I have managed to get the milky-way template in Joomla to work and have customized it a little. My concern is the fantastic heading with the balloon.
1. I love the clouds but will need to change the balloon to something else.... Is this 'doable'?
2. Do I have to install something special to get the movement or will this just 'happen' once I put install it in Joomla?
3. Where do I find a replacement for the balloon? Is it a normal picture or something special?
I feel stupid asking such elementary questions but I want to convert my site for a demo in the morning and I don't have time to play around with it much. Any response appreciated!!

Hi, Just a quick update for casual passers by - these questions were answered via email.

Balloon can be changed only by editing the flash file.
You do need to upload teh balloon.swf flash file into a module and publish it in the 'feature' module position.
The balloon is a normal picture - but animated in flash.
