[Setup planning] Just to make sure I get it right.. some questions

[zielperson]

Alright, I got to play around with XBMC on my Pi (which had been sitting idle faaar too long) this weekend.

First impressions:
SWEEEEET!

It setup with my Western Digital USB HDD, Edimax wireless, and CEC with the TV Flawlessly, basically out of the box.

Yes, I am using a powered USB hub for this.

What I would like to setup is the following:

The goal
- XBMC Media centre for movies and (maybe) music
- Torrent download machine

The man
I know my basic way around Linux (not an expert, though), so technical explanations are OK.

The plan
(and questions)
I did set up the transmission package via the frontend, but if I get it right this is just a client to view and start/stop torrents.

Question
I have to install, and set up the actual transmission program via SSH, is this correct?

I tested the screen saver via frontend... this seemingly crashed the Pi.. black TV screen, had to reboot the Pi by unplugging it.

Question
What gives? (This is not really important, though)

As for music...
I am eyeing some Bluetooth speakers with AUX in and would like to be able to stream internet radio as well.
However, I have heard that the Rpi Sound ..er... sucks.

Question
Do I route it through the TV via HDMI?
How is the setup done there?

Thank you for taking your time reading this.
And thank you for an awesome product!

Best,
