As someone who works for an Apple reseller (and hence I sell macs to HEAPS of switchers) - I'd say a week or two to get things down.
Apple's Switch 101 website is good for a primer - for the nitty gritty things you're used to on a windows, then how to do them on a mac.
My best advice is to play as much as you can, and use the apple.com's support pages - they're heaps better than anything M$ gives you.
Now, I work in Australia, but I'm pretty sure its the case everywhere - but you can get 90 days worth of phone support when you first buy one - good for a last resort, and they're pretty helpful.
