No, for slice 4, it would be ada0s4.  For the MBR setup, bootcode must 
be added to both the MBR (ada0) and the slice.

bsdlabel partitions are created inside a slice.  No idea whether the 
partition numbers being out of order will be a problem...

gpart create -s bsd ada0s4
gpart bootcode -b /boot/boot ada0s4

Then add partitions inside that:

gpart add -t freebsd-ufs -s 2g ada0s4
gpart add -t freebsd-swap -s 4g ada0s4
gpart add -t freebsd-ufs -2 10g ada0s4
...

I strongly suggest taking advantage of labels with the -l option.
