I have some questions regarding the grounding. You linked to a grounding block but I found some I wandered would also work that I can get cheaper and quicker:

As far as actually, checking it and ensuring everything is properly grounded is this something a handyman could do? If so, is there something concise that I could give to him and say this is what I need done.
Another question is whether I would need anything else other than one grounding block?
