Having your shsh blobs backed up allows you to restore to an older firmware that Apple no longer supports should you "accidentally" upgrade to a newer, yet to be jailbroken, firmware.

Without it your stuck at the newer firmware.

jailbreak, open cydia. cydia will have a link at the top "make my life easier" or it may just back it up automatically.
