I'd choose the setup number 1. With 45 defence you should train in the second level of the Stronghold of Security. Flesh crawlers are also aggressive, but they hit a lot less. You should use 2h while dungeoneering if you don't want to get def xp. About the rapier, if you enjoy dungeoneering, get it. It's a little bit better than rune scimitar and it is worth it if you don't mind wasting some tokens/cash to recharge it every once in a while. Hope I helped. ;)
