(1) SAM will only allow ONE mic/line input.. BUT, if you choose to rung them thru an external mixer, you can use as many external mics/sources as you want, running the mixer into SAMs soundcard input.
(2) This is true. SAM does not play well with many USB devices. It's sort of 'hit or miss' as to which ones work and which do not. It's suggested that any external audio device connected to SAM be a non-USB device.
(3) With your licence (registration key) you're allowed to install SAM on up to TWO PCs. One as your main broadcast machine, and a second as a backup or production machine. Registration keys are verified via SAM connecting to the Spacial Audio registration servers, and will only allow activation of SAM on two machines per each registration key.
