Personally, I think Festinghouse is on the right track.
Depends on what you're doing, but for overnighting, you want scope. I'd say his 3:1 suggestion to be on the low side - most cruising sites (granted, for larger boats) recommend 7:1 for overnighting. A second anchor would be added safety, but also means that much more line (and you guys are already balking at a single 7:1 rode.)
For lunch, I find a 2.5 to 3:1 scope fine in calmish weather (less if staying on the boat.)
My primary hook is a Danforth knock-off with 15 feet of oversize chain, plus 400 feet of rode. I carry a second hook (Bruce knock-off) with 15 feet of chain and a 200' rode. I have another 200' line with no ground tackle I can push into service as well.
Re: anchoring from bow and stern: I wouldn't do this unless I was sure swell and wind wasn't going to swap direction. If the boat ends up anything but bow-to, it could get ugly pretty quickly.
