For road use I like the Shimano A520. It is single sided and has some support. I've also used the A530 which is similar but the reverse side has a large platform for riding w/o cleats. The A530 is heavier/clunkier and I wouldn't recommend it over the A520 unless you often need to ride w/o cleats. The double sided SPD pedals work ok for the road but you don't need the two sides like you do for MTB. I prefer the support and appearance of the A520. Shimano pedals generally come with cleats. When you get your new pedals and cleats installed, take your bike into a narrow hall where you can touch both sides while on the bike and practice clipping in and out. Concentrate on repeatability and consistency. You want to use the same motion, from the same position, each time. I prefer left foot from the down or fully extended position. The proper motion to release is a positive rotation of the heel to the outside. No thrashing about or moving the entire foot!
