well there are some apps in cydia where you can save the springboard exactly how it is and also another few to backup the apps
for backup there are two I know of one is free and the other costs a few bucks.
1. pgkbackup (not free)
2. aptbackup (free)
now I have used both but I dont use any now simply because when I upgrade and use one of the apps some times not all tweaks are compatible so its not always good using it, although it is a hassle remembering all the tweaks you install if its many and just install them one by one and make sure they are compatible with the newer firmware you are on.
the other tweak I mentioned I forget the name of it but look in the tweaks section.. or hopefully some one else will remember it
