So is it best to abandon ifs with === and !==? I think they are great
for validation and flag checking (like setting a variable to a result
set or Boolean false). But I might have gotten ahead of myself using
them too liberally, which is now a bit worrisome and creating a few
problems...and overtime.

No.  What you're trying to do is type hinting, which only works for the
compound types: classes (as of 5) and arrays (as of 5.1). See:
