Every system of manifestation relies on certain principles, so in a way, they all work, just some work better for some people while others work better for others.
One important principle is that Wanting (or giving thought to) + Allowing (or accepting, or being at peace with, or being patient or expecting or believing, or having no resistnace to, or detachment, feeling good about or just feeling good in general) = Manifestation, and they have to add up to be be at a minimum threshold.
I personally have had a lot of success with Creative Observatoin that Steve has written entries on and this way:

As well as an excersize from Silva Mind Control Method.
I also spend a lot of my time w/ IM changing my beliefs and probing my resistance. The Power of Now has also been very helpful in learning to accept and allow and be at peace in general.
I would suggest having a look at a few books (check out your local libary if you have one):
The Law of Attraction by Michael Losier (very good intro)
The Seven Spiritual Laws of Success by Deepak Chopra
The Law of Attraction by Esther and Jerry Hicks
Ask and It is Given by Esther and Jerry Hicks
Also read all the posts Steve wrote ont his topic, in one of them he lays out how he likes to intend. In generall, intention and meditation (whether during or after) seem to work wellj together.
HTH and Happy intending!
