I was wondering if anyone would happen to know where I can find a furnace or a water heater to use with the Sims3?

Curious to know if anyone knows where I might find if this has been created as of yet Gutters and Spouting. 

I know in the sims2 there was a mod for this I used this much of the time.  Is there a mod that is available to keep your friendships stableized and optomized without the relations decreasing?  I have been looking for a mod like this but haven't found any as of yet.

Although probably to early to ask this question, are there any Sim3 sites out there as of yet, besides MTS?  Although the Sims store is open, are there any free sites for Sims3?

Where can I find childrens bedroom sets or bedding or if anyone knows where I can find the bedroom sets that were similar or the same as Sims Squirsts boys and girls bedrooms, mostly I am looking for children bedding. 

using the body builders mesh, will this change all the males in the game to have the body builer mesh or will it just let you create the ones that you wish to use the body builder mesh with?
