LaTex editors and image editors for scientific articles

 Dear all,

After years of keeping notes and mulling over writing articles, I have
finally decided to convert these into actual articles for uploading to
arXiv and other preprint servers.

I would like to know what the best options are in terms of free or paid
LaTex editors to use.

And what (free) software to use for creating images and figures, and
extensive use of math symbols.

The setting for use is a single user.
