>I have a very basic indexing question that I should probably know the answer to but I don't. I know that indexing is great for when using the seek command and things like that. But does indexing also speed up sql statements? Say we have a table called employee and have an index on "emp_no". Then we have an SQL statement, 'select * from employee where emp_no > "500"' If we had an index would the query run faster?

Any available index will automatically be used for a SQL - SELECT. The rule is: use an index, whether it makes the query faster, or slower. Usually, of course, the index helps speed things up. For the exceptions, see my FAQ #8109.
