Without a doubt the process of getting a home loan can be intimidating, especially for first time home buyers.  With this in mind, attempt to know some of the language before you go into the process.  I happened to come across a decent summary of common mortgage terms at Lending Tree that goes over several things to know about mortgages.

In the article, quickly explained are common terms such as principal, interest rate, lock-ins, and discount points.  The list is not exhaustive: depending on your personal situation, you will almost certainly need additional information.

Nonetheless, this particular article gives a pretty good synopsis of basic terms that everyone should be familiar with before they walk into a mortgage lender to attempt to buy a home.
