The light from the Sun is partly blocked by Venus in transit. However as Venus has an apparent diameter of about 1/29th that of the Sun, the decrease in light as seen from Earth is minimal. The decrease of the light from the Sun by the Moon in a solar eclipse is almost total as the two bodies appear to have the same diameter.
When Venus transits, it blocks such a tiny fraction of sunlight that you only MIGHT be able to see it as a tiny dot with proper solar viewing filters. If you have a telescope with special solar filters (otherwise you will burn out your telescope optics as well as your eyes--like burning ants with a magnifying lens), you can see Venus transit the sun this afternoon (June 5th, 2012).
No
The moon can block the sun during an eclipse in the same way as your thumb can block (or eclipse) the moon. A smaller object viewed at a closer distance can appear larger than a much larger object that is further away.
It would during a solar eclipse, but probably not during a lunar eclipse.
There is a solar eclipse when the moon blocks the sun from the Earth. A lunar eclipse is when the earth block the sun from the moon.

During a solar eclipse, the Moon is directly in between the Sun and the Earth; a solar eclipse is the Moon's shadow falling on the Earth.
