I have this last one which is really long/hard. It's so long that I just decided to scan the whole problem. So here it is... and thanks everyone for the help so far!

Two problems are there. Both are solved the same way. With the switch closed, you know voltage across 4R, which means you know current in that branch, and from knowing voltage across the other branch, you can determine the answers in that branch. Now, when the switch is reoppened, the inductor/capacitor discharges through 4R branch.
I will be happy to critique your thinking.
