BC ecommerce fix

I have an ecommerce site that was already designed using BC however I require a quick fix on the individual product layout design. Simply put, I added a space in the design tab and somehow managed to undo the design format of the template which I cannot seem to undo. Unfortunately I do not have the wireframe. But the design was fairly simple and I will be able to explain further. (Sidenote, I made this mistake before and my designer fixed it in about a minute so I imagine it is something quite easy but sadly I don't have the knowledge to figure out) Secondly, I would like a border added to each small thumbnail in the overall product catalogue listing, I have a sample of what I require. and Third, I need to remove two permanent pages. My regular webdesigner is out of the studio and I require these changes immediately and quickly. Please quote ' shell' in your message. Thank you!
