Installation Help Needed

While installing J#, I also installed SQL Server 2005. Is this the same as the current SQL Server Express on the official website? If so, what should I download when I click one the "download now" link if I want all the best stuff shown there? If not, what do I download for the best stuff, too?I suggest downloading SP1, then downloading the advanced services and maybe the toolkit. there is lots of fun to be ahd with that little lot.|||So your saying that I should download all the stuff on the page?|||Just the stuff you think you are going to want, Do you want to create reports? If not then I would not download the BIDS report designer etc
