While it all comes down to personal preference how you set up your controls, their is an optimal setup in regards to economy of motion, and the use of wavelands, rest interrupts, sing-canceling, and DAC techniques.
This is what I am using and believe to be the best possible configuration.
The criteria were: minimal shifts in hand position, all techniques still possible, best setup for interrupts.
UNCHANGED
A set to Attacks
L set to shield: Your left pointer finger should always be positioned on this button, thus it is the best shield.
B set to Specials
C-stick set to smashes: This is really necessary for aerial control and economy of motion in the air. It is simply easier to keep your hand on the a and c-sticks as opposed to moving to the a-button and shifting the a-stick to use retreating aerials. In addition b-sticking has little benefit to Jigglypuff. It is possible to wavebounce, b-reverse and turnaround without the b-stick, you just have to have the tech skill developed. I can do it, ergo, so can you.
Tap-jump ON: This maximizes economy of motion in the air, since you can keep your thumb on the c-stick while in the air. I like it because I think the motion is more fluid, but really, there is no TRUE and UNAVOIDABLE downside to tap-jump.
Z-set to grabs: This lets you DACUS as well as use the pivot boost-grab. It really isn't that hard to DACUS that you need to set this to attacks.
Y set to Jumps: Its easier to short-hop with Jump buttons that with the a-stick, also, its best for rising d-airs.
ALTERED CONTROLS
R set to specials: This removes the need to shift your thumb off the c-stick while airborne. More importantly it is almost essential to have the most possible time to input SDI for interrupts. Not needing to shift to the b-button is really important and necessary to interrupt moves like Marth's forward-b (see Junk's comments in the Marth matchup discussion, this is my answer to that).
X-set to grab: On the ground you're using smash moves less so its easiest this way. Also, I find it makes pivot grabbing easier.
Again, I'm not saying you've gotta change your scheme. I've just adopted the R as special. That said I really think this is best.
