If the units of angular velocity, ω, is expressed in rad/a what then is the units of angular momentum?

L=Iω

From this I can gather that the units are

Is this a suitable way to express angular momentum?

Yes you can express it as such. You can similarly express it N*m*s. You can sort of leave out the radian unit if you wish as that is basically a ratio of arc length to radius.

So if from that I calculated Kinetic energy using

E=1/2 I*ω^2

Where I=1/2MR^2

Yes.
