Recessed Lighting Noob Install Question?? help!
There is nothing physically difficult that a "newbie" could not handle. There are, however, proper ways of doing things to keep within code and safety criteria. There is also a risk to your own safety if you are unsure how to turn off power or how to check for voltages. This is probably not your last house, so you want to be sure you do this correctly. Ideally, you might consider some help from someone with the proper knowledge. There are also many self-help books available. I have found these very useful.
One thing that jumps out at me is the shear number of fixtures you have planned. Depending on the bulbs, this could require enough power (when combined with the power requirements of whatever else is on that circuit) to be concerned about whether your circuit can handle the load.
