Disregarding the "multiple":
"Vector -> Geoprocessing -> Clip" deletes the items outside the polygon
Nope, doesn't. - In my first point I said: */Vector Geometry Processing
Clip, but it wants to extract the data inside the polygon and create a
new file with the extracted data. (To be expected)

You would have to do it for every layer you want to be cut, the
dialogue box will stay open after cutting. If the polygon layer
contains just one polygon, no selecting is necessary.
BTW: make sure all layers share the same CRS (i.e. turn
on-the-fly-reprojection off)
