Descent planning: You're at 20,000ft. You need to descend to 12,000ft at 2,000fpm before you reach a fix. Your groundspeed is 240kts and you are 40nm from this fix. How far out do you begin the descent?

You're hurtling through the sky at 4 miles per minute. Your descent will take 4 minutes. You need to start at least 16 miles from the fix. I'd start at 18 so that I level off prior to reaching the fix.
As for the FMS, I agree. I'll use the planning features on the 430 any time I have one there. If it makes your job easier, take advantage of it.
Prospect, there are a number of things that we do that require math. Much of it comes in the preflight planning of performance and weight and balance. The example I gave was about as difficult as I can do in the plane. I had a flight instructor that once said "If you can't do it in your head, you shouldn't do it in the plane." I think he was right.

Your TOD was easy, just figured 2nm/1000ft, not too bad of an angle really for any jet.
