Converting single non-raid to raid1

[gaf-mNDKBlG2WHs at public.gmane.org (Jerry Feldman)]

With large drives currently at low prices, I am considering buying a
second 1TB drive and setting up a S/W raid1. The procedure is pretty
straightforward by setting up the new drive as a single volume raid1,
then set up LVM with roughly the same sizes, and copy the data to the
new raid1 volume, set up GRUB...

Does the new physical drive need to be the same geometry as the older
drive. Let's say I have a Seagate 1TB, and buy a new WD 1TB drive, will
that cause a problem as long as the raid partition on both are the same
size.

Secondly, is there any advantage or disadvantage to allocating the boot
partition as a raid1. I think in a prior discussion, there was an
overwhelming opinion that swap should be on the raid1.
