Firstly, nope the Ghouls also went east, although it is stated that they spread out in all directions, but their source was Bakersfield. Fallout 3 at best retcons it to explain why they are in DC, same as they retconned the Enclave and the BoS being there, although the BoS at least had a more valid reasoning since they are glorified scavengers. F3 retcons quite alot in fact, i.e. supermutants.
Wrong, the Bakersfield Ghouls were said to have moved to The Gecko, Dayglow, and Broken Hills.
http://fallout.wikia.com/wiki/Necropolis
"The scattered survivors of Necropolis led the Great Migration across the wastes, leading to the founding of towns such as Gecko, Dayglow and Broken Hills. "
No mention of them going east with the super mutants is made in any Fallout game, nor even in the Fallout Tactics intro, what you are saying is 100% made up.
Secondly, Fallout 3 retconed nothing about the ghouls, The BoS, or The Enclave, and the super mutant "retcon" is only based on it being a different strain, its not even a retcon, just an expansion of past lore.

Secondly, no, FEV has a effect on the mutation, although it does not directly cause it, it is one of the effects. Supermutants were dipped in pure FEV, unaffected by radiation. The FEV that got blasted into the air was similarly changed by the radiation though, hence not causing tons of supermutants. The biggest change that FEV had was that it made humans who had been subjected to the outside immune to the effects of the pure FEV. Thats why the Master needed pure humans to make Supermutants, thats also why the Enclave used a modified FEV sample in their initial attempt to wipe the earth clean a plot that resurfaces in Fallout 3. So unless you want to declare all Fallouts non-canon, FEV has a effect and has a direct cause.
Wrong again, as both The Master, and Harold, had been out in the wastes for years, and been exposed to both radiation and FEV, and BOTH were effected by the FEV in Mariposa.
Exposure to FEV in the air does not make one immune to vat based FEV, it only makes one less likely to come out as a smart super mutant. Indeed, The Master made many super mutants with exposed humans before he created his theory that he needed pure humans for it to work better.
Furthermore, the modified FEV used by The Enclave in both Fallout 2 and 3 wasn't used because of being exposed to airborn FEV made people immune to anything, that is pure hogwash. They used the FEV because it was a virus they already had, and because it could be easily modified to attack certain genetic markers, aka mutant ones, which included both FEV related, and non FEV related mutations, and becuaase exposure to RADIATION messed up normal FEV.

The initial idea for "FEV explains everything" was simply to explain how animals mutated as rapidly, rather than simply going through the general stages of evolution. Radiation has a effect, but its not exactly instant. Ghouls are the best example, they are still human essentially, so while the radiation may have turned them into ghouls initially, the FEV kept them alive and facilitated their long lifespans and the whole being healed by radiation thing. Fallout is based on 50s Science Fiction, but it still needs a explanation beyond "radiation" as otherwise you have the problem of explaining why people arent all turning to ghouls eventually, or in general mutating into something else.
Except New Vegas proves that theory entirely wrong, in both the base game, in Camp Searchlight, and in both the NCR and Legion nuked areas at the end of Lonesome Road we see instantaneous ghoulification.
There has never been a point in Fallout lore that said ghoulification took a long time, in fact, it has always been described as taking several years, at most, to less then a day.
FEV never was used to explain them living long enough to become ghouls, as ghoulification NEVER took that long to begin with, in any Fallout game.
As for why not everyone turns
A. There is a genetic X factor.
B. Most people don't stay in high radiation areas long enough to be effected.
C. The radiation levels of the world have gone down to the point of normal, present-day, background radiation, thus meaning one can go outside and not mutate like the ghouls, who were people who went outside directly after the war, did.
