Before I start on building this, does the angle of the fork look correct?

If I understand correctly, every frame is designed for a fork with a certain "rake". If that Easton fork has a different rake than the original, it may result in slightly less than ideal steering and handling characteristics as per the designer's ideal. It "looks" OK. I have built up more than 30 bikes from used frames. When the frame comes with no fork, I try to match the rake of the original. On occasions when I have not matched the fork rake to the original, I have had no problems and detected no detrimental bike behavior. Hope this helps.
You can always contact Cervelo or look at the frame's specs on line, find out the rake of the original, find out the rake on that Easton fork and see how closely they match. If it were me, I would build that puppy with that fork and ride the dickens out of it!

It's hard to say. Cervelo used a straight fork that angled out from the crown, whereas the Easton fork curves. The rakes on the two may be the same, but they could look different.

A few mm difference in rake isn't going to make a huge impact on handling, so I don't see any reason not to build it up.

You can put forks with different rake angles and stuff in a bike if you want. It will alter the ride characteristics to varying degrees. If it doesn't ride to your liking then it's not a big deal to take the wheel off and remove the stem and drop the old fork and in with new. Headset might be a little more time if you have to deal with that. But still you already have the parts. See what they do.

To the naked eye it looks ok to me. You may want to have someone look at it in person if you have doubts.
