He wants to SHRINK the partition, so he will have to resize the
file system, then shrink the partition.

Just resize the file system on sda1 to 3GB (or another value which leaves 
enough space - just overcalculate here). Then make the partition smaller 
to the final size you want it to be, then re-erlarge the file system to 
it's final size.

And another advice: Do NOT create the new partition(s), before you 
completed the TWO resize-steps.
