Final answer:
For English grammar, use 'out-of-the-box' as the correct adjective, 'full-time' when describing employees, and 'seriously' as the adverb. For comma placement, ensure commas are used before coordinating conjunctions in compound sentences and after introductory phrases, but not between a subject and its verb.
