Helllpppppp!!

1) Due to delayed travel to the UK after entry clearance, I have not been able to complete 5 years (few weeks shortfall) but I may still be granted an ILR as per the rules. However, I don't see any section in the form to explain this situation. Should I attach a separate cover letter?
2) Should I staple the form?
3) Section 6.2 (absence sheet): I have too many entries to put in that would not all get into the table provided in form. Do I need to fill in the table provided before continuing on separate sheet or just leave the table empty and just attach a sheet?
Thank you very much for your help guys!
