Everything I've read says the main issue he had with the government was it's policy towards aiding the imagined Muslim invasion. He also hates marxists and those in favour of multi-culturalism. But his crusader analogies, prayers etc - are all directed towards his irrational fear of Muslims.
So, yes, I do see his Islamophobic views as a main part of his terrorist motivation.
In his bizare mind and logic, he says that Muslim and Paki-bashing is counterproductive - again his words. He saw the left as 'jihad enablers' (and therefore bought in to the hate-filled ideology of Spencer - whom he cites many times - and Pam Geller).
All of this is clear from the evidence in the media, and can be checked by looking at the references to his manifesto and the diary entries.
I am not speculating, just reporting what the evidence so far reveals. You seem to be wishing he wasn't Islamophobic etc. But, if I've missed some evidence you've read - I'll be happy to stand corrected. Just quote his words.
Edit:
For example, this NYT article makes the link quite clearly:
The man accused of the killing spree in Norway was deeply influenced by a small group of American bloggers and writers who have warned for years about the threat from Islam, lacing his 1,500-page manifesto with quotations from them, as well as copying multiple passages from the tract of the Unabomber.
..
His manifesto, which denounced Norwegian politicians as failing to defend the country from Islamic influence, quoted Robert Spencer, who operates the Jihad Watch Web site, 64 times, and cited other Western writers who shared his view that Muslim immigrants pose a grave danger to Western culture.
