Is this possible?

[DiehlsDeals]

I have self-taught myself some web design, but get lost when it comes to the really complicated scripts. Or at least they are to me!

Basicaly below is my problem. If anyone can help that would be great!

I have purchased a domain name. I belong to a site that delivers my products and has the catalog on their server. I would like to have that site load within my new domain, but have it still remain on their server.

this way the purchaser's can still have all the shopping features that they used on the previous site, without me completely remaking the site or even having the site in my domain really.

Another issue:

I would like to remove something from the site from showing or updating in the new site. The current logo and store name and put in my own, and so I am clear this is my store name and logo for the previous site, which they won't let me chanage. Will this be even possible? Without making the redirect stop functioning?

I may be confusing whomever is reading this, so if you get what I am asking THANK GOD!
