Propeller Proto Board Questions

Hey there,
I was wondering if someone could tell me if the servo connections in the top right corner of the Proto Board PCB are connected to any particular pins of the microcontroller. If not, that's fine, I'll pick my own pins, but I'd rather know before I start fiddling with it.
Seeing as this is my first prototyping board (other than the regular copper track ones you get from your local electronics store), what is the usual method of connecting the components that you place in the holes. I noticed that only some of the holes are connected together, the rest are all sort of solo.
If I wanted to add a bigger reset button, I need to connect pin4 (connected to the reset pin on the controller) of the usb2ser to ground. However, when I look at the board, there is no numbering of pins on the PCB near the usb2ser port. Which way should I start counting. From top to bottom or vice versa?
This is a really terrible ascii art impression of what the propclip, propplug and usb2ser connectors and power socket section of the board look like. I hope it is clear enough.
From what I gather about the mechanism of resetting the controller, I would momentarily short pin 4 to pin 1 of the usb2ser connector. Am I correct?
Gr,

Edit: Being not so experienced with the kind of soldering required on those boards, I should recommmend you solder male or female (according to your preferences) multi-point connectors to the proto board and piggy-back the boards you are accustomed to. This has a lot of advantages, especially the ease to recycle the proto board...

The usb2ser pinout is slightly different from the prop plug but I've figured it out now. Thanks though [noparse]:)[/noparse]
I'll be making a small addon board for the prototype board to allow for a larger reset button. I've tried in vain to train some ants to press the on-board one for me, however once they started forming their own union, I could no longer afford to keep them.

One more level of quoting would've ripped a hole in the time-space continuum, please make sure to never exceed four levels, mankind's survival depends on it.
