Does it involve cutting out the drywall, or fully surface mounted? Anyone have any suggestions to ease this kind of upgrade? How to install a pico in a wall box?
You can surface mount a pico or put it in a wallbox. The adapter that mounts it in a wallbox can also be used to surface mount it with a claro faceplate... you can also just mount it on the wall with no switchplate. Check out the pico sell sheet: http://www.lutron.com/TechnicalDocum..._SellSheet.pdf
To allow you to upgrade to a full keypad in the future, which needs a wallbox and power, I'd follow your electrician's advice and put the pico on top of a wallbox that is prewired with 110...

A) Does the 10 watt minimum vs the 5 watt minimum in any way affect the minimum light output achievable by the dimmer/lamp combination? B) What's the best choice in dimmer for new construction? It kinda looks like the 6CL is targeted towards retrofit with the 2 wire feature, but I'll have neutrals installed so maybe I should use the 10NA with the lower 10 watt minimum, but then I'm missing out on the low-end-trim feature. Then again, that shouldn't be a problem with good LED lamps, right?
3) Does the 10NA allow more LED fixtures on a load? I'm guessing not since it's the inrush, not wattage, that necessitates the limit, but wanted to check.
4) Suggestions on LED lamps that work well with RadioRa2 dimmers? I'm sure this discussion has already happened, but it's not coming up in search. Can someone point me to it? Is it better to pick my dimmers first or my lamps first?
I'm not an expert on this, since I don't like the way LEDs dim (the color temperature stays constant, even at low levels, unlike incandescent which takes on a pleasant yellow glow at low levels)... Lutron has very detailed spec sheets on how many different LED lights perform with their various dimmers.
It seems there is a lot of debate around the best dimmer... I've had people tell the the 10ND and other people tell me the 6NA... Both of those are about $50 (list price) more expensive than the 6CL... The 6CL should be able to handle a load as low as one LED bulb, so even though it doesn't have the neutral, minimum load shouldn't be an issue. Read back through here, i believe Paul posted fairly recently saying that he did some testing and the 6CL dimmed LEDs more nicely than the 6NA...
I'm doing retrofit and using mostly 6CL (even though I'm 90% incandescent), with the expectation that as LED tech matures, the 6CL will allow me to upgrade to LED...
