Update, my experience only.
1) I was able to disable (via a form of theirs (blockchain.info), they did it in an hour) the Google Authenticator 2FA. At their wallet home page I went to "Settings", they have a cool way of offering a second password that is required if sending BTC out -- it is cool because you do not type in the p/w, you click it letter-by-letter on a virtual keyboard that they show on-screen. So, I do have 2FA of a sort, if someone tries to take the BTC, it is harder. Fair enough.
2) I have another wallet using SMS texts as a 2FA process. This just worked OK, but I limited in the number of SMS texts I can get/use (maybe my cell plan, I don't know). I could probably use THIS wallet as a "Savings Account", to be accessed relatively rarely (say, less than once per day or once per week).
Bottom line is that I have reasonably functional 2FA using both techniques mentioned above. I wanted to experiment with 2FA because of the horror stories and as a pre-emptive defense againt keyboard logger programs (etc.).
I appreciate the replies! Thanks!
