simply go into the design of the form, click on view then properties and set the 'record selectors' choice to 'no' to remove the row selectors on the left of the form( if your using continuous forms) or the 'navigation buttons' choice to 'no' to remove the bottons on the bottom of the form. B
Bear in mind the user will not be able to change records after this, only one form record will be in view. Generally, I only use this option if I'm opening the form after a user has made a choice to see a particular record, and only that record.
Hope this helps !
