not understanding 7 segment multiplexing

CrossRoads:
Here's what I mean.
I layed out 10 LEDs, 2 resistors, a connector.
The board layout looks like it.
Yours just looks like a bunch of holes that are connected, can't tell what it is.

I'm a beginner so you have to bear with me learning my way through eagle.

so if I go per http://arduino.cc/en/Tutorial/ArduinoToBreadboard minimalist approach and don't use a resonator/crystal, it will function at 1 MHz, right?

so 9600bps serial in code will actually be 9600/16 = 600bps?

If board space gets tight, I may need that extra little bit of space in leu of resonator. Didn't realize how hard it was going to be to fit all this stuff on a 2" square board. I'm gonna see how far I can get.
