Tip #1: Address your questions to Calfee directly; Netizens, no matter how well-meaning, won't honor your warranty.

If you're certain that the seat posts won't install properly because the seat tube's aren't the correct diameter (i.e., you've checked them with your Vernier caliper), call Calfee and get their recommendation on how to proceed.
Now, here's where that part about being careful taking advice off the internet comes into play... If it was me and I had checked both the seat posts and seat tubes and determined that the seat tube IML was out of spec, I'd simply ream them out to the correct spec. However, you're not me and I'm not going to pay to fix your frame if you do something that Calfee didn't instruct you to do.
As for your other issue again, if it was me, I'd work up a drawing of the frame with my saddle installed (Ok, I'd mark up a photo using Photoshop & PowerPoint) to figure out what my options were. If there was enough of my seat post exposed, it could be that a custom-made stoker boom with a very steep angle might work. If not, then it could well be that an unconventional boom would be needed. Again, the key is getting everything on paper in terms of where the bars need to be in relation to your saddle to figure out the best way to get from point A to point B: it may be a right angle, then again... maybe not.
