Setting up location w/ special projection

I'm having a little trouble translating the following projection info
from Arc/Info, into a grass location.

Teale Albers projection parameters:

projection albers
units meters
1st Standard Parallel:     34 00 00
2nd Standard Parallel:     40 30 00
Central Meridian:        -120 00 00
Latitude of origin:        00 00 00
False easting (meters):           0
False northing (meters):   -4000000
Datum:                        NAD27
Spheroid:               Clarke 1866

My questions are:
1) What does grass mean by Central Parallel?  I guessed at giving the
difference between the 1st and 2nd parallels. But...

2) How would I set the latitude of origin as the equator?

3) How do I set a false northing?

4) There doesn't seem to be anywhere to set the datum.  Is NAD27
assumed under aea?

Thank you all, especially those who helped me with compilation problems.
