All scientific papers should be written in Latex. This ensures proper formatting and makes your work look more professional. Some general resources on using LaTeX can be found here:
For conferences, you will usually require a style file for your latex document. IEEE style files can be found here:
These days you should not be going through postscript (ps/eps) to get to PDF files. Try to use "PDFLaTeX" to directly make your papers into PDFs.
For some examples on using LaTeX packages to add pictures, pseudocode, subfigures, macros as well as various tricks to make your document prettier, here is a link to some sample documents I made:
Use Vector Graphics whenever possible. Unless you have a photograph which is naturally a raster image, make sure to use vector graphics (typically PDFs) for images in your documents. They are sharp at any size and typically much smaller in size than rasters. So, all charts, cartoons, explanations etc. should be vector graphics. In fact, even if you do overlays on your pictures, its better to bring the picture into PowerPoint, do the overlay text/arrows there and then save as PDF. The
Tikz package is an excellent way to produce good looking graphics entirely from within LaTeX.
