Now I don't want to appear paronoid

, however I think I am being set up somewhat. Can't go into too many details.
But questions for our resident computer security experts.
How easy is it to get stuff off someones computer remotely?
How easy is it to put stuff on someones computer?
What are the signs of keylogging?
How easy to read someones emails?
If I take my pc to an expert, would they be able to tell what has been passed and where to?
