Is there any way that I can easily over write the last 2 lines of a file in perl without having to rewrite the entire file?

If you're using fixed length records then you can seek to the appropriate spot. Otherwise you'll need to rewrite the file with the correct data.
Read in the old file, and output the new over the old, replacing the lines you need replaced

Thanks Mark, I was hoping to get around doing that, but I guess I'm stuck.

I suppose you could also 'seek' to the end of the file, backup until you get to the third newline character, then write the two new lines. If the new lines are shorter than the old lines, you might have to 'truncate' to get rid of the extra text.
I don't know how efficient this is.
