Hello! Congratulations for migrating from M$ Windoze to Ubuntu. You are outside the matrix now, be welcome!
About your challenges, i can do most of them, but i am sure you will want to do everything once you know how to proceed. a few points cannot be done on Ubuntu, but there are equivalents and workarounds.
We can do the whole list in ten hours off support, plus many dead times, for example:
Me: type command sudo aptitude install xxxxx
You: Ok, done
Me: Ok, lets wait 20 minutes while it installs...
