I did know that they hadn't filmed them yet, but I think if American Idol wasn't on almost every night, they might have sped up the production process. Fox ordered the new episodes in September.
I don't see how American Idol being on TV had anything to do with the production process of Glee. But by the point the back nine episodes were commissioned I'm sure the cast already had other commitments anyway, so they couldn't commence filming immediately. For example, Jane Lynch was contracted to appear in Love, Loss And What I Wore on Broadway from October 21st to November 15th.
Also, the Glee kids took part in various signings across the US from November 2nd to November 7th. The first of these signings featured all the main kids, however the other ones did not feature them all as some had prior commitments.
In addition, it's very rare that a 22 episode TV show films all 22 episodes back to back. Usually the first batch are filmed, then there is a break before picking up the final episodes. I can imagine this will be the case even more with Glee considering the extensive time it takes to film in addition to acquiring the rights to each song (which is only done after the episode is written), rearranging and recording the songs, and choreographing the numbers. This will take even longer with the back nine as the number of songs per episode is increasing from five to six up to eight to ten.
I would also imagine that the back nine episodes, whilst they probably had plot outlines, were not written until they were picked up in September. They would have to allow time for the episodes to be written before the production process can begin. (Though hypothetically even if all of the episodes were written, they would not have been allowed to continue with any other part of the production process until the green light was given to the back nine, as there was no contract to produce episodes, therefore no staff.) The production process with regards to the musical numbers alone begins six to eight weeks before each episode is filmed.
So to be completely honest I doubt American Idol had anything to do with it.
