I'm going to assume you are not lazy and are really just struggling and don't know where to search (Tons of stuff on the internet).
First my opinion about putting. Putting is the easiest part (to at least 2 putt, and hopefully at least scare the first putt by the hole) IMO. I mean you can blow a drive, blow an iron, duff a chip, etc but putting requires no defiance of gravity.
1. Start visiting the Instruction Forum at Golfwrx and search putting. Tons of great stuff.
2. Find out if you are left or right eye dominant. (Clue: left eye dominants have a tendency to pull putts left and right eye dominants tend to push putts right. Some say the offset in the blade putters is not good for left eye dominants and we should get zero offset putters since we look at the face more)
Visit this link for a quick test. http://www.wikihow.com/Determine-Your-Dominant-Eye
3. Lookup Edel putter fitting and see the laser test they use to find out where your aim is. You could be left eye dominant and aiming to the right, you never know. Normal is for left eye doms to aim left. (Hint you can do it yourself with a friend.)
4. Hit up puttingzone.com and read the tips.
5. Here is a post someone really liked on golfwrx I posted. I personally am using a right hand dominant push stroke. It frees you from lines and spots and what not and let's your right hand flow to the target. I am also experimenting with the position of my right thumb behind the club to brace the face more.
Post#7 (I am using a cheap lightweight blade RAM putter for the best results. Might go to an expensive lightweight blade though possible offset too, we shall see)
In short there is a wealth of info on the subject of putting. For instance, Geoff Mangum of puttingzone.com says that a perfect pendulum stroke require manipulation of the hands/arms etc. I believe him. Most golfers should have an arc.
Here's another tip, make sure your lead hip, specifically the ASIS (the curved bone on the front of the pelvis in front of the hip that sticks out the most does not move in the putt.
Point is if you have the will to learn the science of putting there are plenty of things to experiment with. I personally got tired of aimlines and crap one day and just started pushing the putts toward the hole with a light putter on a path my eye told me was good. I still miss a few 5 footers and what not but my distance control and aim are much better flowing the ball to the hole.
P.S. Geoff Mangum has a video "The Reality of Putting" available for 25.00 on either puttingzone.com or secretinthedirt.com He also has a book Optimal Putting for 10.00 which is some really cerebral stuff.
