There is a wealth of information here on SRP and links to great video. Use them it will make your learning so much easier and quicker.

Bottom line you will need your 1K and at least a 4/8K combo stone. With those 3 stones you are set. You can add some Chrome Oxide and any kind of strop for the next level of comfort.
Learning to strop is as important as learning to hone. You will strop every day.

Pyramid honing is simply honing on 2 grades of stones alternating from a higher grit to a lower grit and back to the higher grit. What it does is smooth out the edge by flattening the high spot on the land of the stria. Honing grit creates a valley, the groove and the corresponding hill the land, (land/groove). The goal of polishing is to progressively reduce the high spots and smooth the edge. Pyramid honing is just one way to accomplish this.

Sending your razor out for Pro honing is highly recommended for new honers because it give you a baseline, something to compare your honed razor to.
