how do i configure  intervlan routing on an existing topology ?

good day
KIndly refer to my attached network topology of the site
the network topology consists of 3 sites connected to each other via serial micorwave links
the tasluja site is responsible for routing the trafiic between the other 2 sites ( bas and head office)
the tas and baz sites, each consists of 9 or more access catalyst 3550 switches. each connected to a core 4507r switch which is then connected to a 2600 cisco router which is then responsible for carrying traffic to the other site using the micro wave links, all switches including the core has been assigned with dynamic ips using the DHCP server, therefore all VLANS configured on the switces are native VLAN1
- all switches including the core has been configured withethe default settings
- i have been assigned to finetune the network, first i had to decide how to manage or address VLANS since all departments access or share the same resources, i have been told that there is a near by project to handover ip telephony to the site later, therefor i should put a VLAN for voice into assumption!
- However, the ip address schemes of the site is as follows
for TAS 10.232.0.x--- static ips assigned for servers and default gateway (router)
10.232.1-2.x -->> this hould be dynamic ips assigned by the DHCP to the hosts and switches

for BAZ -- >> 10.232.100.x--static ips assigned for servers and default gateway (router)
10.232.101,102.x >> this hould be dynamic ips assigned by the DHCP to the hosts and switches

for head office-- >> 10.232.200.x ->>static ips assigned for servers and default gateway (router)
10.232.201,202.x -->>this hould be dynamic ips assigned by the DHCP to the hosts and switches

the routersstatic ips are  
TAS router-->>10.232.0.1
BAZ router -->>10.232.100.1
HO router -->>10.232.200.1


i have been given a range of 10.232.3.x for TAS, 10.232.103.x for BAZ and 10.232.203.x forHO to assign static ips to tehe switches for management  instead of dynamically being assigned from DHCP

my question is as follows:
- i need a case scenario or case study with configuration examples, lets say if we have the following
2 catalyst access switches --> core switch-->> router -------- seria  link ---- router<<--core switch <<--2 access catalyst switch

- want the core switch to handle the inter vlan routing
Vlan 1 ( native) for managment
Vlan2 for Data
Vlan 3 for Voice
- How should i configure this regardless of the ip address assigned?
- Kindly give acase scenario with config example or kindly apply configuratuion scenario on the attched topology
- I know its a little bit complex but i need your help and experties especially that the deadiline for this task should be only be the end of this week!
 - i also need some finetuning like :
- where to apply port security, VTP pruning, STP,RSTP and all of this stuff on switches giving some configuration examples
_ also What configurations should be made on the router, core switches and the access switches to manage routing of VLANS bearing in mind that all of them are catalyst and multilayer switches?
