comment Integral $\int_{ \ 0}^{\ L} \exp{(\frac{-(x-x_0)^2}{4n})\sin({m\pi\over L}(x-A)}\ \mathrm dx$
Mathematica 9 gives a result for this integral. It's quite long and in terms of the imaginary error function.

comment $\int_{0}^{\frac{\pi}{2}}\cos{x}\sqrt{1+\tan{x}}dx$
Another form of this integral is $$I=\int_{0}^{1}\sqrt{1+\frac{y}{\sqrt{1-y^{2}}}}\mathrm{d}y$$ and maybe it can help.

@DanielFischer Good point, I totally missed that. Maybe it helps!

comment Closed form for the following sum
$|B_{2p}|$ is the absolute value for the Bernoulli numbers. I've tried splitting it into 3 sums and fiddling around with the bernoulli numbers, but no result.

comment Infinitesimal $SO(N)$ transformations
Yes I know (personally I don't like to write in this manner), but I wanted to keep the same notation as the OP used.

comment Formula for Sum of Logarithms $\ln(n)^m$
Some years ago I found this expression $\sum_{i=1}^n\mathrm{ln}^2i=\mathrm{ln}^2n!-2\mathrm{ln}n!\mathrm{ln}(2)_{n-2}+2‌​\sum_{i=1}^{n-1}\mathrm{ln}i\mathrm{ln}i!$. I can remember having some troubles to compute the last term $2\sum_{i=1}^{n-1}\mathrm{ln}i\mathrm{ln}i!$, but maybe this result sparks some ideas.
