I will double check those items in the morning.
However, doing a quick check on the Orc, it looks like the costing on the Orc is correct. It appears that you caught a typo. Charisma should be -2, not -3. If you look at the rest of the text of that paragraph, it explains that the total of the negative mods should be -4, while the total of the positive mods should be +7. I had thought that I had changed that. Come to think of it, I may have changed it, but that may have been right before MS Word crashed on me the one day (prior to the changes being saved, and I missed redoing it once I had Word back open).
As for the Kindred Talents, it would help if you were a bit more specific. However, please note that in most cases, I tried to halve the power of the ability and then halve the cost as well (Favored Skills being the primary exception here, but it is QUITE possible that I missed something). So please, give specific examples, so that I can specifically double check them and be sure.
