lol was gonna put that link, but ninja'd
just follow the guide as you install, as there's few things you should do to optimize the ssd
and yeah, don't defrag, the benefit is marginal to none, but ssd can wear out faster with that.(still it'd take years though)
its recommended to disable anything disableable that is write intensive/space consuming on ssds, like hibernate etc, but thats in the guide too.
to use integrated gpu you would need to switch the video outputs, as motherboard outputs igpu, but gpu outputs itself.
