Of course, better be safe than sorry. Decoupling shouldn't ever negatively affect a circuit so can always add more.
Now looking at good values for that inductor - never used those things before so their values have little to no meaning to me. The link in #13 mentions "tens of milli-H" which appears to be a huge value, very big expensive parts for larger currents. Reading a bit more and I see decoupling inductors with tens of micro-H values. Makes me wonder... probably that's an error in that blog, and I need to look at the micro-H range rather than the 1000 times bigger milli-H range.
