I use Assos chamois creme and i don't have any problems with it. Which is fantastic because i'm allergic to all kinds of showergels.
Believe me the difference is huge on long rides.
As for padded shorts I wear assos (the absolute best but very expensive), shimano and bioracer (but the last one is perhaps not available in the US).

bioracer

The last two brands are 50% cheaper than the assos. They are more than ok.
