Setting up QoS on a variable speed connection (512kbps night/256 kbps day)

    Sorry if this sounds like a n00b question , but I am pretty much a n00b when it comes to this...
    My home network is running a WRT54g v5 running DD-WRT v23sp2 micro firmware with 4-5 clients (fixed IPs in the 192.168.2.x range ) connecting to it.

    The WAN connection is from an ISP called Airtel (India) which provides me 256/128 kbps from 9:00AM-9:00PM and 512/256 from 9:00PM-9:00AM

    Am thinking of setting up QoS (Quality of service ) rules on my home network as am pained by manually slowing down torrents whenever I need to browse or use VoIP
    However, have a few doubts and would appreciate the help of anyone who has any experience on this...

    While setting up the QoS rules, let us say I Allocate torrents service to Bulk, Http to standard and VoIP to premium or express.
    This would leave me with specifying the maximum upload and download limits, which I presume the router will use for the bandwidth allocation calculations..

    Now since my connection is @ 256kbps (day) and 512kbps (night), what happens if:

    A) If i were to set 256 as my d/l speed, would the router still allocate the full available bandwidth (512) to torrents at night when no other network activity is happening? or is it that since I have set 256 as the d/l speed, the router would throttle the available bandwidth to 256 for torrents thereby leaving the remaining 256 unutilized?

    B) If I were to set 512 as my d/l speed, I suppose the router would allocate all the avilable bandwidth (512) to torrents at night, but during the day, when the speed is 256, the router would still allocate a more than necessary bandwidth to Torrents (On a base calculation of 512) and leave little room for the higher priority services

    ANy suggestions welcome!

    Thanks Masterbeto, but not sure how this script generator would help...
    Additionally, this script only allows for IP based traffic shaping rules while I need to set service based rules

    Anyway , I suppose I could use the HTML interface of the router to make the changes to the settings instead of runningg a script...

    My primary question though is what settings do i use?
