A family friend wants me to re-do his website. It is an old website basically just made in HTML only. I'm a recent college grad with experienced in ASP.net and Visual Studio and such. Re-making his website is definitely do-able, but there's just some basic procedural questions that have me confused.

If I wanted to re-do his website, but in a way where I'm working with what already exists (the pictures, text, domain name, etc), what information do I need? Do I just need the user name and password to the hosting account and FTP his old web developer used and that's it?
