Hi ,
There are many methods for identifying the last row & column.

You may want to check these links before trying out a particular method.

1) http://www.mrexcel.com/td0058.html
2) http://www.ozgrid.com/VBA/ExcelRanges.htm

For the code to unprotect the sheet & insert 10 rows, just a record a macro
for the same & use that code.

Thanks in advance for any help,
