That indicates you're abusing multiplot.  You should almost certainly 
have either used the secondary y axis to do both plots in one diagram 
without multiplot mode

	set ytics nomirror ; set y2tics	
	plot 'data1' u 1:2 axes x1y1, 'data2' u 1:2 axes x1y2

or you could have re-scaled one of the datasets on-the-fly:

	plot 'data1' u 1:2, 'data2' u 1:($2/5.0*14000)

Whether that's true depends on what you mean by "show up".  The gnuplot 
core does try to draw those things --- in versions up to 4.0, it partly 
depends on the terminal driver what happens if they're outside the 
visible range.

That set aside, you probably should have use 'graph' or 'screen'
coordinates, not data-driven ones, to positions those labels. See "help
coordinate".

Not very strange.  LaTeX (or rather the graphicx package, to be precise) 
does depend on the filename extension to guess what type of file you 
have, and what to do with it.  If the file's called *.eps, LaTeX can 
peek inside and find the BoundingBox.  If it's not *.eps, LaTeX expects 
to find size information about the image elsewhere.
