First of all I want to commend you on your decision to wear your baby! Research shows that babies who are "worn" cry less, are able to calm self better, develop good postural control, and are exposed (in a very good way) to variety of sensory experiences :)
While I don't have personal experience (yet) with baby wearing, I've being doing a lot of research on the topic. Thought this info may be useful...
here is a site that compares various brands of wraps and slings and tells you which one is meant for newborns or older babies/toddlers, etc:

This site tells you how to make your own wrap, and give info to people who are new to baby wearing:

here is a site with ring slings/pouches. It has a lot of great video tips (e.g. shifting your baby's weight in the sling:

Good luck!
