I definitely think they are worth it and you should consider them. I don't think you should worry about killing Nomad; I was able to kill him first try with 94 att/str, 99 def, soul split (no turmoil), a pure set and void melee. So with your stats you should easilly be able to knock him over; simply run behind a pillar when he uses a special and brew up for the one you can't dodge. As far as the soul wars cape, it's really great to have for whenever you need a decent prayer bonus. I know you said apart from the prayer bonus, but if you get it and get a slayer task where you just have to pray (say spectres or spirit mages), you will notice just how much slower the drain is. For the rapier, I didn't think it would be worth all that dging just for that. I got one recently though, and it definitely is. I've been using DGS since around 70 dg, and from around then I think you'd be fine to use it. As long as you can do abandoned floors, you should be able to get a decent amount of dging done. It really wouldn't take too long, I didn't want to do much dg but for the last 100k tokens decided to just get stuck in to it. It turned out to be quite enjoyable, and I got the tokens in 3 days, not spending all day dging, although I was on holidays then. So I think you should definitely consider them both. Short answer - get them both.
