阅读此段文章，但内容和文法结构不太理解，望请大大们解惑!!!
谢谢大家
There may have been some consolation in the fact that the bid came in $1 million
below the revised budget and $5 million below the original budget of $29 million
formulated in mid-1991. However, the final cost was the considerable sum of
$ 24 million, the bulk of which was paid for by corporate and community
contributions, merchandising, licensing, and the proceeds of lotteries, with
the NSW Government, which had originally been willing to spend up to
$10 million, contributing some $ 2 million. The Federal Government's grant of
$ 5 million meant, in effect, that the Sydney bid was financed by every
Australian taxpayer.
想请问黄色句子部分:
1. 付钱的是corporate and community contributions，
支付的项目是merchandising, licensing, and the proceeds of lotteries
的意思吗?
2. with the NSW Government, which had originally been willing to spend up to
$10 million, contributing some $ 2 million
a) 这句是NSW Gov.贡献了$2 m，而他原本是愿意花$10 m的意思吗?
b) 为什么some 和$ 2 million中间不用介系词啊?
