Video tutorials would be sort of useless, since all ways to make maps require some text editing or at least command line usage. Our main docs are found on our wiki here: http://wiki.armagetronad.net/index.php?title=Map_Making
I thought you already asked that. You make a spawnpoint by drawing an arrow (just a line between two points, I don't remember exactly what happens if you use bezier curves or multiple points, but it's probably nothing useful).
It's much better to use normal lines (“paths”) for the walls that limit the race areas than rectangles, otherwise you'll get four walls, three of which are pointless.
Also, Zones aren't represented by circles (inkscape saves them as paths which makes it impossible or at least hard to extract the radius). You instead use the same format as for spawn zones, but with a start marker instead of an end marker. You can use those circle things instead of arrow tips.
To mark a zone as winzone or deathzone you need to use a perfect red or green (#ff0000 and #ffff00).
Yes, lines can have a color. Either use the “stroke paint” tab in the fill and stroke dialog or right click on the colors of the pallete at the bottom.
And you can make a straight line by clicking at the start point, then at the end point (NOT dragging) using the bezier tool (Shift-F6)
Well, I don't know just how patient wrtl is, but *I* would not want to do the work for you. Some of it (replacing rectangles with lines) sounds like a lot to do, and really, doing it yourself will give you valuable skills for the future.
