i'm also wishing to get on with cathay pacific. just finished a Second Officer initial interview with them last week, now hoping to hear about a second interview in HK.
www.pprune.org is a great site for information. to get on to the passenger fleet you must start off as an SO, but on the freigher fleet you start as an FO, however they require previous jet experience for that. i believe starting pay for an SO is just under $50,000US/year + housing allowance. not sure on sched, or any of the other stuff.
hope that helps a bit.
