Hello,
well i have set my Raspberry (B) with ArchLinuxArm. I decided againts
gentoo, because of the long compilling time (for example git takes a long
time). Maybe i try gentoo on my second sd card...

A1: I have set an extra swap partition. I followed this guide for resizing
my main partition (i have a 16 GB sd card class 10) and setting the wap
partition (or rather swap file?): Raspberry Pi – Partition an größere
Sd-Karte anpassen [1]
It is in german, but i think that if you are using gentoo, you should be
able to follow just the commands, knowing what they do.
I am not sure, how much swap you need, because you maybe need space for
compilation of programs. Because of this fact i would encourage you to set
a swap. How much swap you need/can give depends on the sd card. (I
wouldnt't make 1GB swap on a 4GB card).
I look forward to hearing more of you, because there are not that many
people, talking about gentoo on raspberry (or rather i didn't found many).

Can't answer A2, and A3, not enough knowledge.
