It'll probably be fine where it is yeah. BTC-E does have a hefty fee on withdrawing LTC at the moment, so it might be best to wait until they lower the fee to withdraw your LTC....that is assuming they'll ever do that though. Personally, I wouldn't want my currency sitting in an exchange or a pool. Both exchanges and pools have been hacked/had issues, but that doesn't mean they will, and I couldn't say if any of those that you mentioned OP have been in the past.
Though a wallet is the safest bet.
You could keep your litecoin at
https://Cryptsy.com and move it for .03 LTC compared to .5 LTC at BTC-e
Either one will keep your coins safe.
