Lego Star Wars: TCS help

I really need help on Lego Star Wars: TCS. Some of the achievements I don't really understand.

Set off all 3 discos? Where are all the discos?

Max out the stud counter, how do you do that?

Can anyone actually give me a link to a guide that would tell me where all the red bricks and mini-kits are and how to get all the achievements?

Thanks.

the discos should be in the kamino level in ep2, the pit of carkoon level in ep6 and i can't remember the third one

as for the stud counter all you have to do is get 4,000,000,000 studs which is dead easy if you have the 2x, 4x. 6x, 8x and 10x multipliers activated as they combine and you will have an overall multiplier of 3840x.

hope this helps
