Nothing that I am aware of.

As long as your /tmp does not normally exceed your RAM size it might be
a good idea. Still, it is not really SSD specific: It will of course
save a few writes, but as long as /tmp is always smaller than your RAM,
there are obviously not that many writes anyway.

Using today's Debian you do not normally need to bother with alignment
as all partitions will be automatically aligned at 1 MiB boundaries by
most of the tools anyway.

None of the modifications is "necessary". You can simply replace a HDD
with a SSD without having to worry much. Still, a ramdisk for /tmp could
be useful (also in HDD environments).
