Not sure about the gain level issues, but it sounds like the issue with the FX in the beginning of the chain has to do with input impedance. See the advanced manual pages 2.5 - 2.7. http://line6.com/data/6/0a06434dfb244f7b7f489af64/application/pdf/POD%20HD500%20Advanced%20Guide%20v2.0%20-%20English%20%28%20Rev%20A%20%29.pdf
If you are using "auto" impedance, the Pod is switching the impedance to the closest impedance matching the actual impedance of the modeled effect that the input signal is first routed to. Amps and most effects are 1M. The 2 you referenced are 22k. That's a huge difference. The tone will be much darker and looser feeling with those effects first in the chain.
You can override this by going into the system menu and changing the impedance setting to 1M (or your preferred setting) instead of auto. Or just don't place those effects first. And this can be made a global setting or per patch.

Great point man - I know that the Impedance matching feature was added recently, but I've always left it globally at Auto. I didn't realize that it affected the FIRST thing in the chain. Good Catch! Thanks for the tip.
It does affect the change in volume between input and FX send, and ONLY in a negative way - When set to Auto is where the 2.8 dB difference exists, and starting from 3.5M all the way down to 22K only reduces the volume difference from 2.8 dB down as much as 6 dB. There is still a definite difference between input and FX send, even with the most ideal parameters.
