I think even if you're a new quilter, those blocks are well within your reach, especially in a quilt along where there is so much help and enthusiasm from others.
My advice, (Which you didn't ask for, but here goes anyway...), is to really think about your colours as you have to look at them for the next year or so. (Unless you are doing it scrappy...each block different.)
For something like this, I usually buy a print that I absolutely love for the border and then pull my colours from it for the blocks. Be sure to have lots of contrast and, if you are doing a light background, spring for a really good fabric that will be the least see-through. We all try to "Press to the dark side", but it isn't always possible. Err on the side of caution and buy an extra 1/4 yard of each if you can...you don't want to run out and you can always use it on the back.
Have fun!
