How do your plugs & gap look?

I also had these issues almost a month now, car was showing me running lean code(1st CEL) cleared the code at my friend's shop, after a week CEL came on again(2nd CEL) showing running lean still, cleared the code at my friend's shop, i was still observing the car. After a couple of weeks (3rd CEL) came on again showing random misfire/running lean so i brought it back to my friend's shop and we replaced the spark plugs(was pretty damn bad) prolly still the original plugs(car has 78Kmiles) also seen hairline cracks on the ignition coils, cleared the code(9/1/12). After that week took the car for a road trip(9/9/12), ran around 250 miles. No CEL so far until Saturday morning CEL came on again Misfire on Cylinder #2(4th CEL)(9/15/12) so i decided to order a set of ignition coils, i just bought the
BECK/ARNLEY Part # 1788427 ordered from RockAutoParts $192.31 set shipped. Anyone had use this? And just tonight borrowed my friend's scanner scan the car it gives me codes misfire on cylinder #2 and P1399 Multi misfire. Anyway, im still in the process of troubleshooting it though i know its slow, but i don't drive the car daily and im a very busy guy due to my work so it can wait. I only use the car every mon/sat with just around 5-30 miles total for a day. Hopefully its just the coil packs, i'll do the coil swaps tomorrow just to double check if its really the major trouble. I will also update you guys when my coil packs arrives and if it solves the problem.

I would highly suggest valve adjustment.
