That sounds like a great deal the sump could be bigger for your tank "bigger is always better" when it comes to sumps but yeah I would jump on that. I would wash everything in a bleach solution and get rid of the bioballs I would replace them with LR but that is just my preference. A sump is a much better way to go than a canister in my opinion
