About Swissair and Boeing: keep in mind, that Swissair never was a big Boeing customer. Apart from the 2 B742 and 5 743 I don't recall a Boeing aircraft in Swissair's fleet.
As for the numbers: officially Swissair has 9 A346 on order. This is according to Swissair website. An american leasing company (ILFC or GECAS?) has announced some wees ago, that the will lease 3 A346 to Swissair. So far I don't have any confirmation, if those are new A346, or 3 out of the original order for 9 A346.
So far, now swap to A345 was published or rumoured. I don't know any currently operated or planned city pairs out of ZRH, which would need an A345 instead of the A346.
The MD-11 are already sold to FedEx, as already stated here.
Hope it helps
