You have already chosen to change status from H4 to F1, if in case you file H4 along with your H1, whichever approval comes later is valid. If F1 is approved in January 2015 and H-4 is approved in February, which would supersede the earlier F1 approval making only H-4 is valid.
No need worry about the pay checks since you are employed in that particular company on the day of submission of the application.
