In San Francisco I can often find fresh yeast at the local health
food store (Rainbow Grocery) or at Whole Paycheck...I mean Whole Foods.
Not that I ever use the stuff. I use instant dry yeast. Here are some
rules of thumb:
* 1 oz. fresh yeast works like 0.4 oz instant yeast (some people say
0.33 oz....)
* 1 oz. instant dry yeast fills 12.5 teaspoons
With a little math that should be all you need to substitute one for the other.
Soft wheat vs. hard wheat are general terms for different strains of
wheat. But home bakers will be hard-pressed to find out the strain of
wheat used for a particular brand of flour...although here are two exceptions:

Soft wheats do tend to have less protein than hard wheat, so I might
be tempted to ignore the author's advice and use AP or cake or a
mixture of AP and cake flour. I've heard that some of the flour
brands popular in the south (White Lily?) tend to be made of soft
wheat 'cause those varieties grow better down there.
