You're just about there. All you have to do now is shrink /dev/mapper/nala-home's LV. lvreduce -L301G /dev/mapper/nala-home (the extra GB is so you have some extra room for the filesystem)
you could have used lvreduce instead of resize2fs lvreduce -L300G -r /dev/mapper/nala-home you may think about resizing it back out and letting lvreduce do both at the same time so that you don't truncate your file system. Then you can extend the LV for nala-var if they are on the same Volume Group: lvextend -L+49G -r /dev/mapper/nala-var (size may need to be adjusted as it may not work out to exactly 50G, run pvdisplay again and multiply the "free PE" number and the "PE size number" and divide by 1024 and it should be about 49 GB). if the -r gives you trouble run it again with out it and then run: resize2fs /dev/mapper/nala-home and it will fill out the available space. I'm using Fedora 17 so you may want to look at the help for your distro for the switches lvextend --help or lvreduce --help.
