getting started with funnelIO through arduino

hello
i just recieved funnel board i purchased for its "all in one" potential
but now i understand i need lots of other items to set it working

any of your comments will be helpfull since the ressources about this board are rather obscure...

first -
can i use an arduino board without pic to set the xbee working before i insert them in the funnel... (and how should i proceed)

can i use an arduino (with/without pic) board to talk directly to funnel through TX RX (i think i saw a picture on mr kobayashi's flicker showing a possibility to enter with a usb to serial interface)

and if i manage ? will i be able to use through the arduino IDE?
i've downloaded the funnel_009rc2 package but there is no clue for me to have it "hello world" - ing .....

(those questions to avoid to buy boards and cables and wait for the mail)

second
why should i solder that something they say i should on the funnel board (close to the on off switch) ....

to mr kobayashi ... why is that the 1st thing to do ? why not a jumper like the DC/usb alim switch on freeduino....

...

please ...
help my project to go wifi

i have ten days to set it working or i'll go back to the wired arduino solution....

!!!

thanks
