Is your wallet passphrase encrypted?    If so, at least steps 1-3 can be done and tell you how much of unspent funds there are.  Since the funds can't be spent without the passphrase the wallet can be shared without requiring a high level of trust. 

If you do have it encrypted, you might want to change the passphrase if the current one is one that is sensitive information (e..g, used elsewhere, in part or whole).

Just make sure you make a backup of your wallet.dat before doing anything else to it.

If it isn't passphrase encyrpted, then it should only be shared with trusted individuals.
