I would make a test block...just enough to make one. Figure out your hiccups now before you cut out all those blocks. Chain piecing is exactly how I'd make this too...and I've been quilting for ten years.
Whether you chain piece or not, I'd make the first block first. And I wouldn't cut all the pieces at once, but that's just me. I get bored cutting, then I get bored piecing, so I alternate it. It's probably not very efficient but it works for me and also gives me a chance to see if I'm doing something wrong before cutting all that fabric.
