nothing in the Linux world is ever easy. ;)  but it's worth the work.

do you already have this hardware?  i hope you didn't just run out and
buy it for Myth; not that that's a bad thing.  just that it seems like
you've got some stuff you don't really need for a MythBackend...

the KnoppMyth forum is probably the best place to get KnoppMyth
specific questions answered.  if you don't get a response to your
question look it over and make sure you are asking it clearly and are
clearly stating your intentions.  a lot of posts get ignored because
ppl don't really understand what the questioner is really looking for.

also make sure you check out the KnoppMyth wiki: http://knoppmythwiki.org

since you do have three drives you may want to use one for all your
Linux related system stuff, swap and your cache (ringbuffer).  maybe
your scsi drive for that.

that's up to you, actually, both are up to you.
since you have multiple drives i would set one up as your
system/swap/cache drive and then lvm the other two as your /myth
partition.  or the other two could be set up independently as /myth/tv
and /myth/video for movies...  you've got all kinds of options. :)

i'm using XFS on my /myth partitions.  there is a pretty good how-to
in the knoppmythwiki that explains setting up LVM.  it is actually
pretty easy.

hmm, first i think you need to figure out what you really want to do. 
what are you going to use this system for?  anything other than Myth?
if you really don't have any Linux experiece you may be better off
starting off by setting up a basic combo frontend/backend machine and
trying it out.  once you feel comfortable navigating the filesystem,
reading logs, etc you can create a separate backend to play with. 
there's no right way to do it, this is just the approach i'm taking.
i think a lot of ppl will be hesitant to give you a step by step for
anything until they're clear on exaclty what you're looking for; not
because they don't want to help, but because there 'are' so many
different configurations that will work.
i hope this has been somewhat helpful. :)
