Which one goes first when applying for a job? any tips?

Like if they ask me if i am applying for other jobs which I am should I be honest?

Then any tips for interviews and stuff and what they want to see?

btw i am applying to ... Subway

and i was wondering in my resume where do i put i have a food handlers certificate

So I got this cover letter, resume and application. Which one do i staple on to

cover letter then application then resume or what?
COVER LETTER AND APPLICATION LETTER ARE THE SAME SO FIRST APPLICATION LETTER, RESUME AND THEN THE CERTIFICATES. FOR YOUR INTERVIEW YOU SHOULD BE HONEST BUT CONFIDENT. IF YOU DO NOT KNOW THE ANSWER TO AN INTERVIEW QUESTIONS THEN YOU SHOULD SAY YOU DO NOT KNOW THE ANSWER. WHAT YOU SAY DEPENDS ON WHAT YOU RESUME CONTAINS - NEVER EVER CONTRADICT WITH YOUR RESUME. ALWAYS RE-CHECK YOUR WORDINGS ON THE RESUME, MOST RESUMES HAVE PROBLEMS WITH CONTRADICTING WORDINGS. MAKE IT SIMPLE THAT YOU CAN ALWAYS EXPLAIN. ALSO, YOU NEED TO DO SOME LITTLE RESEARCH ON THE COMPANY YOU WILL BE WORKING FOR SO THAT YOU CAN ANSWER ANY QUESTIONS THEY MAY ASK REGARDING THE COMPANY. HOPE I HAVE BEEN HELPFUL. BEST OF LUCK IN LOOKING FOR A JOB.
