Bluelamb and Dingo...worlds apart Mystery Cache

Just Under 50 (L to the romans) I Am Now

...well, 9 years under but I just wanted to make Bluelamb03 feel better :)

Bluelamb03 was born Nov 3, 1956 in Feteira, Portugal in the Azores
I was born Dec 7, 1965 in Chatham, Ontario
(we were both born at noon!...well not really, but it'll do)

The listed starting coordinates are irrelevant.
They happen to be for a travel agency called “Golden Mile 2000”.

There are two points(call them 'Bluelamb' and 'Dingo'),
both derived from our birthdays that share the same longitude (arbitrarily)
The longitude of said points is:

W 075 AB.400

...where AB is 1/2 Bluelamb's hometown North degrees (whole) added to 1/2 my hometown North degrees.

The latitude you will have to figure out.
You will ultimately figure out 2 numbers,
each when divided by 100,000 will give you the exact minutes of the latitude of each point.

The cache (see next line) is at a bearing of 74 degrees true from 'Bluelamb' and 84 degrees true from 'Dingo'
Aug 25/09: Add .020 to the north and subtract .010 from the west of your calculated GZ to find the booty

Since Bluelamb's (inherited) 50th bday cache (GCZ50T) went AWOL, this should make up for it.
Also, The Burrow beat me to it with the 1st commerative cache for Bluelamb's 2000th find,
but hopefully he'll have fun with this one too!
Useless factoid:
If his 2000th find was represented in years it would be his Bimillennial!
Update Jan 13/08: Congrats to Bluelamb03 on making this his 3000th find!

...oh, and there is a FTF prize of an unactivated 1701eh coin waiting...will it be Bluelamb?
Update: Cron got the coin!..well done!
