Hi,

a)

Plot3D[0.075 +
    0.916*(1/
       Exp[-Exp[-0.075 2]])*0.01 let Exp[-0.01 let] + (1 - (1/
          Exp[-Exp[-0.075 2]])*0.01 let Exp[-0.01 let])*1/(0.05 t +
        1) /. let -> Exp[let], {t, 0, 100}, {let, 1, 2.698}]

should do the Log[] Scale of the let axis.
What means "add points" ??
Do you want more PlotPoints ??

Transparency is only possible with Mathematica 6.0
and

Plot3D[0.075 +
    0.916*(1/
       Exp[-Exp[-0.075 2]])*0.01 let Exp[-0.01 let] + (1 - (1/
          Exp[-Exp[-0.075 2]])*0.01 let Exp[-0.01 let])*1/(0.05 t +
        1) /. let -> Exp[let], {t, 0, 100}, {let, 1, 2.698},
  ColorFunction -> (Hue[#3, 1, 1, 0.5] &)]

would do that ...

Regards
   Jens
