 To find out what that 150mb of first-time boot space is used by, you can mount the usb stick on another linux system, and then inside of it's root dir you'll see a file called "casper-rw" of the same size as the persistence file you created. That's actually an ext2 filesystem-in-a-file, so you can mount it to a dir with "-o loop" as you'd do for a cdrom iso. Inside you will see a file structure mimicking the main one, but only containing files that have changed since the original squash filesystem was made.

 The good news is that you can recover about half of the space by dropping the databases if you don't need them.

 The situation is much the same as the above, but the base system has grown to the point where persistence on a 4gb usb stick is not feasible, but should work out of the box on a 8gb usb stick. Actually there is 83mb available for one on a 4gb usb stick, but 150mb is automatically taken up soon after you first boot. It is possible to unpack the mini iso's squashfs as is done in the gisvm/build_chroot scripts and remove a few hundred MB of stuff by hand which you don't need, then repack as a new smaller iso, but that 150mb is still eaten, so you'll have to clear out more than you might think. The min persistence file limit has already been lowered to 256mb for you in this release, and it is not suggested to go any lower.

 The USB System Disk Creator tool that comes with Ubuntu 12.04 has a minimum persistent disk size of 1024 megabytes.
