Evidence of lawful residence

[freshgasflow]

I am filling form AN to get British citizenship and have an appointment on Saturday. Regarding evidence of five year lawful residence, the form at the end says to provide:
Your passport OR Letters of employment etc ...

So I have not bothered about the letters. However, now when i read the guidance note (separate booklet), it says :
• Your passports OR say why you are unable to provide one on page 13 and supply
• Letters from employers, educational establishments or other Government
Departments indicating the applicant’s presence in the United Kingdom during
the relevant period OR ....


Now I am confused and panicky. Do I need to get those letters or not ? I will find it difficult to get them in such a hurry ....
Please advise me !

It's either (a) passport or (b) explanation and letters from employers etc. The passport should be fine.
