You said IDE.  Don't expect problems unless you want to worry about
a worn-out disk.  When you "make a filesystem" on the disk (mkfs is it?),
it has an option to check for bad blocks and, IIRC, to mark them bad
so they won't be used.  That still doesn't protect you from marginally
bad parts of the disk that only occasionally act bad.  Some (rich) folks
don't use disks that have been used a lot for more than about three years.
With home systems, I wouldn't worry about it.

No. All manufactures seem to put out good and bad disks at various times.
Some folks have their most- and least-favorite lists, but lists contradict
each other.

Ensure your old disk has it's "jumper" set to "master" and your new one
to "slave", per your owner's manual.  That's all you need to begin.
Boot up Linux off your old diskk or floppy and "cfdisk" (or fdisk)
should see the new disk and allow you to partition it. Then make 
"filesystems" on the partitions as needed using mkfs (?).  Then add
entries into your /etc/fstab file as desired.  (All this assumes you
just want to use your new disk for expansion, not a whole new OS, etc.)

Traditionally, tar is used. I've had some bad luck with moving
socket files. I'll use "cp -a" next time.  The only thing I know
to give serious problems in a move is that if you delete a
shared library that the OS needs, things will stop working.
The / partition must normally be copied, the copy edited so that
it will boot up OK, maybe LILO reconfigured and rerun for the
new boot, and then reboot to the new source.  It's all too 
complicated to explain briefly.  Many people have done it tho.

I'd try to keep everything you need to run the OS on
one disk, so you don't increase the probablilty of a
disk problem from disabling you.  Or, better yet
put a complete bootable minimal Linux on one of your
first disk's 50 or so MB primary or logical partitions
to use as a rescue system to repair damage to the other
partition's software.
