I wana try to help my friends out a lil bit on here with some of the achivements. Just give ya some pointers on them.
The most recent one I done was (Polishing party Mega Extreme) Polishing 10,000 bling in 24 hours.
This one really hurt my hands and was rather boring, but still needs to be done to get to level 57.
What I done first was loaded up a few tab with people I found in the Hottest Fublingees section, Because they have the most bling and u wont waste time searching while ur polishing. Stay on their page I started with their LE bling for points then movied on to their normal bling.
U want to hit the expand button on the upper right hand corner of the bling box that way u dont have to scroll so much to see more dirty bling! THIS IS VERY IMPORTANT to save some time.
Even with doing this and taking a few breaks for obvious reasons this still took me 2 polishers and 10 hours to do.
Good Luck :)
