Painting sharp mask lines ... and few easy/quick questions.

Hi,

1)Is it possible to paint in sharp mask lines while brushing on your mask? The lines while masking seem to be blurry. I know you can ctrl+alt+click to sharpen the edges but they don’t give what I want too often… (eg: i mask an oval and need the edges sharp)…
2) What are alternative/better methods to work similar to masking out objects before sculpting, but I need the edges to be sharp?
3) when I’ve masked a shape like a hole, how do i extrude/move it straight up along its normal?
4) when i sculpt, the red dot of the brush point seems to snap on to geometry/vertices… how do i turn it off?

thanks

Mesh needs to have sufficient density to mask on for your needs as well.
