RA 5h 55min, DEC 7 deg 24 in
The distance ("a") from Earth to Betelgeuse is about 427 light years and the distance ("b") from Earth to Rigel is about 772 light years.
The angle between the two stars from Earth is 18.56 degrees.
Knowing these three numbers, we can now use the "law of cosines" to calculate the distance (c) between the stars: c = square root of (a2+ b2- 2ab x cosine of the angle).

Today ... February 1, 2010 ... Jupiter's celestial coordinates are:
RA: 22H 21M 41S
Dec: -(11° 07' 01")

yes
How do you measure the location of a star?
Using a method similar to latitude and longitude on the surface of the earth. The corresponding terms are declination and right ascension.

The closest terrestrial analog to hours of right ascension is angle of longitude?
yes. latitude is to declination, as longitude is to right ascension.

One hour of right ascension is equivalent to how many degrees of sky rotation?
Depends on the declination in question. There are 24 hours of right ascension in 360 degrees, so at the celestial equator (declination = 0 degrees) 1 hour of right ascension is equal to 15 degrees. But as you increase or decrease declination the right ascension lines converge to the celestial pole (like longitude lines on a globe). The angle covered by 1 hour of right ascension is therefore equal to (15 degrees x cos(declination) ), so at the celestial poles (declination = +/- 90 degrees) 1 hour of RA is 0 degrees.
