Brand new / totally confused / am I in the right place?

I downloaded MS SQL Server 2005 Express Edition. The MS site said that it was "easy to install, use and manage." However I'm totally confused. I'm not a total neophyte but I can't even seem to launch the program.

I have an MS SQL database powering my website. I view the database on my home computer using MS Access 2000 with an ODBC connection. MS Access 2000 however, does not let me make changes to the structure of the database. I can't add, delete or modify fields in my current tables. I can't add or delete tables. Is MS SQL Server 2005 Express Edition the proper software to perform these functions? If it is, is there a guide to helping me launch the program, connect to my MS SQL database and perform these functions? If this is not the right software, what is?

I would greatly appreciate any guidance anyone can offer.

Thanks!
