How many access closets and how far are they to your distro closet? It looks like you have to use fiber for your uplinks from access to distro, if that is the case, then you will need a collection switch (distro) like 2 3750s with 12 Fiber 1 Gig ports each. So, you could use the 2960s as your access switch and use the 1Gig SFPs to uplink them to your 3750s. Keep in mined that 2960s and 500 switch are 10/100 for user connectivity and the uplinks are only 10/100/1000 or SFP.
It really all depends on your budget and the requirement
For a 48-port PoE switch (other than 3560E & 3750E), you have 370 watts of power. You can use 48-ports to power up at 7.0w or 24-ports at 15.4w. The only switch models that can power up 48-ports at 15.4w is the 3560E & 3750E.
A core switch using 3560g-12D/3560G-12SD or 3750G-12S with IP Services IOS feature would be recommended.
Well, i know 3750-E is expensive, but i need layer 3, i want to stack two switches (maybe three in a future), and yes, i want 10G uplinks (i will connect two uplinks to a NetApp FAS Platform). So, i think, 3750-E is the best option, expensive, but the best.
In the access layer i want POE, voIP, QoS, and to aggregate uplinks via LACP or etherchannel. As i will need 8 10/100/1000 24-port switches, not too much complex, not layer 3... well... 6 units of 2975 switch will be fantastic, but... very expensive... and 8 units of esw 500 model... they seem ok.
