I have an iphone 4 which I want to jailbreak, can I save the blobs before I jailbreak it and if so please tell me or point me to how to do it if anyone knows?

Use TinyUmbrella is my suggestion. Or Redsn0w but that didn't work out very well for me.
Remember to uncheck the SSHCydia in the advanced tab (as I've been instructed).

Yes you can get the SHSH's beforehand.

see above, use either redsn0w or TinyUmbrella.
