iPod restore question

OK,, seems apple is giving me a brandy spankin new 30g video for my troubles.

this fiasco all started when i updated the ipod to whatever they suggested. right then things went straight to hell.{error 1418} i did do a full back-up before i started trying to reset, restore reboot, redo re every-dam-thing.
my question now is this: when the new ipod finaly gets here,, should i be worried about loading the back-up onto it? will it load whatever the hell screwed it up in the first place? and i will be right back there again?
i am thinking i should just start from step one.
any advice will be appriciated!!

i used "tune tools" to do the back-up. it gives you a choice of a ;quick backup', or a full backup'. am i wrong in thinking that a full backup has more than just music? maybe it has the couple gig of software apps as well?
i'm thinkig i will lean twords the cautious side and start from scratch.

i do manualy manage my songs. my library is all but empty. i don't play music in itunes, only ipod and my laptop is almost full, no room for the library.
so i do a backup.
edit: my new ipod is said to be up to date. i would hate to inadvertantly reload the problem that came with apple's update! my backup could possibly hold the corrupted update? any chance you would know how i could tell?

update,{cuz i'm sure you all want it.}
the new 30g video is now in a suitcase and headed south.
one question:: what is the normal waiting period before i can expect the "sorry dude, we *****ed up, how can we make it up to you" response from apple?

now that i think about it,, i think i would like to send them a personal bitch
e-mail. can someone give me an address where someone might actuly read it? at apple of course.
thanks!

thanks,, what could it hurt?
