Yes, previous contributions are not a 'must have', but additional
benefit. If you haven't played with criu previously a quick start
up guide is https://criu.org/GSoC_Students_Recommendations

Absolutely. I'd also add that knowing Linux API is often needed
badly. In particular, if choosing the 'optimizing the pre-dump'
task, one would need to get familiar with Linux mm API including 
mmap(7), contents of the /proc/{pid}/maps and pagemap.
