You can increase and decrease LVM volumes. Increase is easy and almost 
all filesystems are able to increase size at runtime. Decrease is 
possible, depends on the filesystem/data you are using within the volume.

Yes. That's possible. To do that you only have to add the new PV (your 
Raid 1) to the the existing VG. You can even move to other storage at 
runtime (pvmove). But again - if you want to use the full feature set of 
LVM you have to do it on the shell, not with the webinterface. It is 
essential that you understand how LVM works. (maybe this can help
