You could also use grub on raid1. The problem is installing it. You
had to trick it to believe you were installing on sda1 (and once more
for sdb1) and that would be hd0 on boot (where the mbr resides). That
way both disks are bootable.
I hope the latest grub-install script does that for you now.

If I need to resize swap that is always temporary for me and then I
just add a swpafile.
