Sounds like your on the right path. I have a fleece pea in a pod adjustable pouch, and I have not been able to carry Liz in the cradle carry ever. She hates it. So I snap it tight and slip her down in, head up against my chest. There's enough fabric so that it comes just over the base of her neck, and provides head support. You can't do a ton of things wearing a small one like that, but it does allow for more movement than not using a carrier, and you can wear them a lot longer than you can carry them.
I'm also still searching out wrap info. She's 2.5 months now, so she's awake more and interested in the world, but still wants to be close to me. The PIP is more of a "sleeping carrier" for us. I think i'd get a lot more versatility with a wrap.
