I won't advise you what to buy; but I can say what I am doing.
Yesterday I sold all XPMs, most FTCs and would have sold LTC if I had any left (sold earlier). I plan to get back in again after price drop. I already had quite a bit of WDC and getting more whenever I am getting good prices (anything around 0.0001 is good, below that is golden).
I haven't looked into the other coins on your list. Somebody mentioned quark - I do have mined quarks in my wallet from ages back. Maybe now I will sync and sell. MEC, CGB and ANC seem to get attention so may be good, but I haven't followed those markets.
Protoshares may be a good buy. I hold quite a few from mining, but the price may already be too high if you are a new investor. I am not selling now, though.
Good luck on your investments
