"So I can connect my Servos directly to the Servo connections on the Prop BOE without anything else, correct?" - for short runs (less than 1 foot) yes. Anything longer it is recommended to place a 1k to 4.7k resistor in series with the servo signal line to lessen any antenna effects that can cause 'servo jitter' problems.

OK. I guess I need to find some female headers or shorter jumper wires with the female end on one side.
I don't think so. I've had lots of problems that look like "jitter" but so far I've always tracked down the problem to being a bug in my movement algorithm which causes the servo to jump from one place to another without making a smooth transition from one position to the other.
Another common problem I've had is with power systems not being able to meet the current demands of multilple servos as the start to move.
I have had at least one brand of servo that wouldn't recognize the 3.3V logic with a series resistor (IIRC it was a 4.7K resistor) but the servo would recognize the 3.3V logic without the resistor. My present philosophy about resistors on servo signal lines is to not use them unless I experience the jitter Beau mentioned. So far, I haven't seen a need for them in my projects.
You might try using a ferrite bead on your signal lines if you experience the antenna effect mentioned above. It will suppress the unwanted high frequencies (noise) without reducing your signal voltage as a resistor will.

It's the object I use whether I'm driving one or 32 servos.
JonnyMac also has a servo driver in the OBEX (I haven't used it myself) which should work fine with the PropBOE.
So I can connect my Servos directly to the Servo connections on the Prop BOE without anything else, correct?
Also, Can I use an 8V Wall Wart for power to the Prop OE instead of batteries?
As long as the jumpers next to the servo connections are set to "5V". And yes a wall wart is fine.
I put heat shrink tubing over the 9V connector after having a barrel connector short to "+" connector.
OK. I guess I need to find some female headers or shorter jumper wires with the female end on one side.
For what it's worth, I just about never use a series resistor with my Propeller / servo projects (including my hexapod).
Do you notice any of the "jitter"Beau mentioned?
