Is there an easy way to capitalize the first letter of a string and lower the rest of it? Is there a built in method or do I need to make my own?

TextInfo.ToTitleCase() capitalizes the first character in each token of a string.
If there is no need to maintain Acronym Uppercasing, then you should include ToLower().

string s = "JOHN DOE";
s = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(s.ToLower());
// Produces "John Doe"

If CurrentCulture is unavailable, use:

string s = "JOHN DOE";
s = new System.Globalization.CultureInfo("en-US", false).TextInfo.ToTitleCase(s.ToLower());

See the MSDN Link for a detailed description.
