Mikrotik LAN configuration help required

Mikrotik Configuration v 6.42r35

Dear Colleagues
Could you be so kind to help a bit with MikroTik configuration., I am more engauged with Cisco equipment and this configutation is created and tested by me quite easy. But historically some sites equipped with Mikrotik equipment. I tried to configure Mikrotik Routers and Switches, read documentations but still somethgin unclear and system does not work properly.
Please have a look at attachement with network diagram.
I would be very gratefull for someone who could send me script or WinBox instruction with configuration for this site. All other sites I could do by myself.
Thank you in advance for your possible assistance.

  1. SVI – Svitch Virtual Interface (like Cisco)
    Access to Switch through different VLAN with different subnets and IPs.

  2. Bridge HW offload.
    Unite all ports to one bridge or divide 24 ports by 4 bridges ?
    There changes starting from version 6.40 regarding bridge HW Offload . So I am a bit confused.
