JDuke:
What you want to do is reasonably simple.
In the query, reference the form and control in the criteria cell for the field to be filtered.
Forms!frmSearchform.cboSelection
Use the usual equals, not equals, greater, etc before the reference to the form.
However, if it is possible that the user will not make a selection from one of you combo or list boxes, you will need to build the a query string using SQL code. An alternative is to set a default value for the selection boxes and, in the query, reference it with the Like operator.
That is a bit too complicated to go into here without knowing the exact criteria you will be using. Post more details and you are sure to get more specific help.
