Is there anywhere I could find coordinates for locations?

Do you mean interiors, like inside the buildings?
If yes - check http://files.sa-mp.com/interiors.txt

No, I don't mean interiors. I mean locations coordinates like, LS Airport, LSPD, etc. Spawn locations coordinates.

If you mean just regular locs go somewhere you want the loc from then do /save goto your documents GTA San andreas user files -> SAMP Savedpositions.txt
