Dear Vangelis,

No problem.  There are many ways to use OSM.  Finding the "right" way
depends on what you want to do, and eventually depends on how you like
to do things.  Let's look at your requirements in a little more
detail.

You want to look at a substantial portion of the northern hemisphere.
You want to show mostly plain coastlines
You want to "overlay some GPS points"
You want SVG output that you can manipulate in inkscape.

Tell us more about the GPS points.
Are these points already objects in the OSM database?
Could they be added to the OSM database?
Are these points or collections of points in the form of tracks?
Is there only one set of points and tracks or do they change at times?
How often will you make a new map?

And about the SVG.
You mention post-processing in Inkscape. Was this to add your points?
Perhaps that can be automated in an earlier step?  Probably more
question about output once we complete the other requirements
discussion.

Best regards,
Richard
