If you have enough other room to install FreeBSD on the disk and that
/dev/hda2 partition is not right in the middle of space you need for
installing FreeBSD. eg, as long as it is in some ignorable place/space
on the disk.

I don't know if ext2 vs ext3 matters. It might. I would be inclined to
want to make a backup of everthing on that partition and keep it somewhere
you can get back to after FreeBSD is installed. Either tar or rsync it
all to somewhere. Dump(8) is sensitive to OS, so it is one circumstance
in which I do not recommend dump/restore for this type of backup.
Now, providing that ext3 thing is not a problem, you can probably leave
that filesystem/partition there if you have plenty of other space to install
FreeBSD and set things up. Then you would probably want to copy everything
from that old /home to a new one in FreeBSD space. You would just mount the
old one as something like /oldhome and copy the stuff from it to whereever
you have space in FreeBSD - maybe a new /home filesystem.
Not so sure I did anything for your most important question - if ext2 s ext3
is a problem, but I hope the rest is helpful.

Yes, absolutely - mount it and copy it to a FreeBSD filesystem if you
plan to use it any amount.
