You model the highpoly and lowpoly models, yep.
Then you UV(texture) map the LOW poly model. The highpoly one does NOT require UVs usually.
Some people first model the highpoly mesh and then creates the lowpoly one optimizing it. Others uses the inverse process ( first create the lowpoly and then export to to ZBrush/Mudbox/blah blah and subdivide + sculpt it ). Both methods have pros and cons, just use the one you prefer
Just sure your lowpoly has UVs before to generate the normal map ( some programs like 3dsmax can automatically UV-map it, but tons of precious normal map texture space will be wasted, is better to do it manually ).
Hope it helped.
