When I changed my belts I did not change the pulleys and of course they became noisy a couple of days later. I think maybe it has to do with the new belt being tight or something.
What year is you car? How many miles ?
For E46, you can get the reflection pulley, but the tensioner pulley is not available if you have a mechanical tensioner and the one for the hydraulic one does not fit. (I tried and got it melted). You can't get the mechanical tensioner either (at least not from BMW) since they "updated it" with the new hydraulic one.
If you don't want to spend $200 + on tensioner, here is where I got a mechanical one:

I only replaced the accessory belt tensioner - I figured the AC works only during the summer so it should last twice as long
No noise or problems of any kind - some 3 months later. I'm only doing filters and tire rotation so I can help you out. I have tools also (wrench for that big lug).
