I had manual drum brakes on my car when I first purchased it, and I must admit - slowing down was a pain. If someone in front slammed on their new brakes, good luck stopping in time before you rear end them.
I did a conversion with stock 1968 front discs, and even went so far as to get a stock distribution valve to avoid any aftermarket pieces. What a difference! I REALLY recommend the discs, but as far as being power - thats personal preference. I stop fine with manuel, and its really not much of a hassle or pain.
I also have power steering...and it's a nice thing to have. Many have mentioned its prone to leaking, but I rebuilt my control valve and replaced and tightened all the hoses and haven't noticed a leak since. Although, I did drive the vehicle for awhile without the power steering pump...and well it was a challenge - one your husband may or may not be up for.
