Get as much information as you can on any and every survey that you can find. Unless you are talking about an over-night project for grade school, you want to make it as accurate and informative as you can. Look for aerial, archeological and or photographic surveys, and anything at all that involves measurements of the monoliths and their locations. See links and discussion
First study the design, its geometric and symmetrical and therefore not difficult to replicate the ground plan. There is a chapter 'The geometry and construction of the stone monument' in 'Solving Stonehenge' which shows you how to exactly mark out the positions of the stones using a compass and ruler. In the Neolithic the prehistoric surveyors did the same thing on the ground using ropes and pegs.
Locate a picture of Stonehenge. Study it. Especially note any angles and curves. Make the pieces with line-edges (squares, rectangles) first, then work more clay on to make curved parts. Use a plastic tool to shape and smooth the clay.

No. It is not clear whether Merlin actually existed.
Nothing really, it was there long before the Romans ever came to Britain.
