I am gonna try setting up my own servers for hosting. But I need a Little advice.

I have a c and d partition. The sites will be on d. But the aspnet_client folder is on the c drive, is this goning to be a problem? And I noticed that if I put the bin folder in the sites root for the dreamweaver controls the page won't work. It's not till I put it in wwwroot that it works. By the way this is Server 2003.
Is there a way to habve the aspnet_client folder in everysite? and the bin folder?

Add the BIN and ASPNET_CLIENT folders to every site in order to make use of them. Make sure you have your ASPNET user account assigned to the websites and also make sure the account is present in all parent directories.
