Here's a site with some info on injection

http://www.wcf.com/co2iron/

I put that link on there because it has a good picture of the Eheim C02 diffuser. I'm not sure it's the best price though. The good thing is that the guy carries everything you need and will answer questions. Although I've never used his product that he claims is a good replacement for a regulator (It's been about 8 years since I bought from him). It is probably fine though, as he's a reputable seller.

Basically, the way I do it is: C02 tank -> regulator (it doesn't have to be a dual gauge one, that is a myth, I've used a single gauge one) -> adapter for tubing -> Eheim defuser.

There's a valve on the defuser that restricts the flow of CO2. There's a porous glass disk on top that basically acts like an airstone. Put a powerhead near the bubble flow for best circulation.

IMO, this is the simpliest and probably the cheapest way to inject pressurized C02
