Hello,
I designed the v5.5 board and built enough of them to tell that this layout works flawlessly.
I chose a DPAK voltage regulator to provide better heat dissipation, otherwise it has exactly the same specs than the SOT one.

I always used windows 7 and arduino IDE only to burn bootloader then upload firmware. Forget about RPi with v5.x versions.
To burn booloader, you MUST use ISP pins. An Arduino Uno board with ArduinoISP sketch uploaded into it would do the job easily. Then connect the board with ISP pins on BlueSAAB. Make sure to use the 5V output of Arduino Uno (3v3 isn't enough to go through voltage regulator).
This page gives you a simple how-to connect them.
This other page would show you how-to burn the bootloader properly, from Load the Sketch.

When all this is done, you could either upload BlueSAAB_CDC firmware via ISP or via USB. If it's via USB (the way I always did), simply remove ISP cables, and connect the board with USB cable. Windows should detect it and install drivers, RX & TX blinking (it will appear as a new COM port in device properties).
Under Arduino IDE select tool 'Arduino Uno' and the new COM port (BlueSAAB is considered like this by software), load BlueSAAB v4.1 in Arduino IDE and then you should be able to upload it to BlueSAAB.
Loads of how-tos are available on the web to use Arduino IDE, if anytime lost...

Hope this helps
