Recessed lighting in the basement

Hello all, I want to install recessed lighting in my basement. The area that I am planning to cover is 23' X 12'. I have few questions and I hope you can help. 1. I am planning to use this spot lights: http://www.amazon.com/gp/product/B008BG6ZUO/ref=s9_simh_gw_p60_d0_i1?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=desktop-4&pf_rd_r=0ER3QYXXP4J8Y1XQY21N&pf_rd_t=36701&pf_rd_p=1970566782&pf_rd_i=desktop Can I use just the spot lights for the entire area or should I use a couple of regular recessed lights and use the spot lights to accentuate? 2. How many lights do I need to install in this area of 23 X 12?
