Maybe you haven't learned how to make a multiple selection yet? Here is a page FULL of tutorials, from the newbiest beginner to advanced SVG coding: http://forum.inkscapecommunity.com/index.php

Probably because there aren't any -- as td already suggested. Although there are ways to make vector objects look like they were painted with raster tools, they are more advanced than it sounds like you might be ready for.
