4) and, or : I think they are left as they are.

$\wedge$, $\vee$

Also $\land$ and $\lor$ ("logical and" and "logical or")

5) implication: if then

$\rightarrow$

Also $\to$

7) negation: $\not$

$\not$ creates a slash through the next character, which doesn't seem to
be what the OP wants. For negation symbols you want $\neg$ or $\sim$.
TeX treats the latter, however, as a binary relation symbol rather than
an operator, so you often have to tweak the spacing with \! to get it
sufficiently close to the next symbol.

Does anybody now a free source on how to write first order logic with
identity and epsilon membership and 'is part of' in LaTeX.

Peter Smith has a very useful page -- LaTeX for Logicians -- with links
to lots of resources, both documentation and code:

http://www.phil.cam.ac.uk/teaching_staff/Smith/LaTeX

On windows try: MiKTeX. Installation is very easy. (I'd recommend
Version 2.6 for a starter.)

See: http:\\www.miktex.org

What makes you think you're talking to a poor benighted Windoze user? :-)

As an editor I'd recommend "WinEdt" (30 days trial period).

See: http://www.winedt.com/

Again, Windows only. Emacs (with the auctex package) is the editor most
people use for composing in LaTeX in the linux/unix world, and good
ports are available for both Windows and OS X.
