Yes, our sun is a G2 V, Main Sequence (dwarf) star.

I don't know of any lists that have been divided up into spectral types
by distance. However, if you're feeling adventurous, find yourself a
copy
of the "Sky Catalogue 2000.0, Vol 1, Stars to Magnitude 8.0". Within you
will find over 600 pages of information on the stars that are 8th
magnitude
or brighter, including spectral type, approximate and/or estimated
distance,
location in the sky, etc.

Note: there are, on average, 75 stars listed per page.	Simple math
exercise
for the reader how many stars are listed in that book. Extrapolate for
the
fainter ones (see Note #3).

Note #2: at a distance of a mere 150 ly our sun would drop below 8th
magnitude and thus not be listed in this catalog.

Note #3: there are a lot of stars that are much, much closer that will
not
appear in this catalogue (eg, Barnard's Star, for example, is magnitude
9.5
but only 6 ly away). Although the majority of these stars would fall
outside
of your desired request range.

Note #4: there are astronomy books out there (I don't have mine handy at
the moment) which do list the '20 Brightest Stars' (and their
distances),
as well as the '20 Closest Stars' (and their distances/apparent
brightness).

horror,
she is finally cornered. Her weapons have been left deep in the bodies
of the
slain or broken against the granite-hard scales of these snakes that are
not
snakes. Her stand to the death must be fought here. Though her only
weapons
are her hands and her deep and wide knowledge of the slayers, she does
not
fear them. They will die. Of this she is sure.
