Brakes and my 59 3100

[Apachemike]

Here's my deal

manual drum all the way around. 350/700r4 I've run into a situation where I need to use the truck for a couple of weeks. It does drive and stop now but I want it a little better.
My choices are:
Just go through and replace shoes and check it all out
Install a power drum kit
Install front discs

Which would be the best choice. If I go discs do I need to change the MC also? This will be done in the driveway and I don't move around as well as I used to.

Thanks
