liteicon + iconfinder.net

1) where is a site that has a proper download for liteicon (can't seem to find one that works...)
2) is liteicon legit
3) is iconfinger legit
4) when changing icons to the one you chosen, and your asked to put in your user/admin pass....is this safe because i heard the only way you can get potential "viruses" are from applications that require your admin pass.
5)thanks, i would like to begin pimping out my dock icons asap if all the above is clean and legit

 

anyone? just a yes or no to any of the above will be useful.
