The formula for the 8-Period Moving Linear Regression is:
AVGC8 + 3.5 * (3.5 * C + 2.5 * C1 + 1.5 * C2 + .5 * C3 - .5 * C4 - 1.5 * C5 - 2.5 * C6 - 3.5 * C7) / 42
The formulas for your requests would depend on your specific Bollinger Band settings. You may wish to review the following:

Bruce,
What is the derivation of the number "42" in this formula. In other words, if I want to write a formula for a different length of time, I think I can figure out the rest of it, but what does the "42" represent?
AVGC8 + 3.5 * (3.5 * C + 2.5 * C1 + 1.5 * C2 + .5 * C3 - .5 * C4 - 1.5 * C5 - 2.5 * C6 - 3.5 * C7) / 42

tedk,
Bustermu covers this in some detail in his Tuesday, April 04, 2006 12:12:34 PM ET post in Using Linear Regression vs Classical Peaks/Valleys for Divergence Analysis. I just add up the sums of the squares of the factors:
3.5 ^ 2 + 2.5 ^ 2 + 1.5 ^ 2 + .5 ^ 2 + (- .5) ^ 2 + (- 1.5) ^ 2 + (- 2.5) ^ 2 + (- 3.5) ^ 2 = 42
The method outlined by bustermu is shorter and more efficient.
P * (P ^ 2 - 1) / 12 = 8 * (8 ^ 2 - 1) / 12 = 42
