About that PC chip: my register always has a true load flag.  What are the ways around needing a true flag, if any?  

It is very common for circuits like counters to have the register's load bit always true. It often requires more gates to take advantage of the load than are saved in the register input circuit. For example, to use the load bit in the PC you would need regLoad = Or(inc, load, reset).
