As we can see from the last two lines above, there is only a minimal gap 
between the start of sda2 and the end of sda1. How did you shrink the 
Windows partition? IIRC, Windows XP doesn't come with tools to resize 
partitions. Maybe your tool reduced the file system size and didn't 
write the new size to the partition table.

Yes, the extended partition is indeed a container for the logical 
partitions from sda5 upwards.

Well, I think the 2047 block gap (~1MB) is left from cylinder boundaries 
and gparted usually wouldn't let you use that gap. As long as the new 
size of the Windows partition isn't written to the partition table, you 
can't enlarge anything.
