6.) With the introduction of D5 and D6 I am presuming that Va and Vb woudl be isolated from each other and would have differenrt values.

Not Quite: the diodes will allow C1/C2 to charge C3/C4 - but not vice-versa.

Thus they allow Vb > Va, but prevent Va > Vb.

In other words, your measurements should always show Vb >= Va

As Stefan says, what limits the current flowing from the mains supply on the right-hand side once the tube has "fired"...?!
