acls & qos for dummies

Hi experts, i need to setup from zero QoS for our voip & wireless SIP phones.
In short, we tryed to place out PBX and all ip phone on a separate vlan, but unfortunately, due different version of IP phone firmwares, we have 50% of phones that can work only to vlan1. We'll upgrade the firmware, but are more than 60 ip phone, so at the moment i'm thinking about a workaround. I added the 10.72.182.0/24 as secondary ip class on vlan1, reserved only for voip, our DHCP server assign address on this class only to  voip phone mac address, so i'm sure that only voip apparate are in this class (i'm thinking at when we'll upgrade the firmwares, so i'll need to reassign the ip class to the voip vlan and in one shot i'll place all voip in a separate vlan).
THE ACTUAL SITUATION: we have all voip equipement on a dedicated lan, that at the momend is a secondary class on vlan1, (10.72.182.0/24). I would like to try to activate Qos to this IP class, is it possible? If it's possilble, what i need to do? I mean i have to use the mls command? I need to build an ACLS? If yes...well...how can i do?
Our PBX address is 10.72.182.1, the SIP interface is the 10.72.182.2 so i need to priorize the traffic of the voip clients to the 10.72.182.1, and SIP clients to the 10.72.182.2 our catalyst 6513 gateway is 10.72.182.254, concerning SIP wireless phone i have a pool of reserved IP. What should i need to know about our IP phones? I mean, for sip i can choose the TOS id, but for the IP wired phone i know nothing. I can understand that it's a poor condition...but if you can give me some suggestion i'll try to collect more info.
That's all for the moment. Thank's in advance.
