Curious as to the amount of Caffeine and L-Theanine in each capsule, could you provide a rough estimate of each please?

100 mg Caffeine and 200 mg L-Theanine per capsule.

I am considering these, but at a lower dose. Are these pills solid that can be broken in half or are they capsules filled with powder?

Check out my response to Luis's comment, but obviously it's you're body so you can do whatever you want. There are other brands on Amazon that sell this same stack but at different doses. Here ya go: http://smile.amazon.com/Puritans-Pride-Caffeine-L-Theanine-Capsules/dp/B00NAWBUHC/ref=pd_sbs_hpc_4?ie=UTF8&refRID=0YMTY1N1XRT72QW09TVVThose have exactly half of what Smart Caffeine has.

How long do the feeling of concentration last from 1 dose?

Let's use today, this morning I took a pill at 9:30. I didn't redose on caffeine (coffee) till 3:55. I would say I felt the slowdown at around 3pm. So it is pretty textbook 5-ish hours that caffeine is rated for. The difference with this pill is besides the non jittery high, the comedown is very easy and didn't feel like a crash, and that's even after a couple of meals.
