Subnetting is always a balance between the number of networks and the number of hosts, so switching to a 10.0.0.0 class would give a lot more hosts but fewer total networks. Are all of the 192.168.0.0/22 using the same range or are some 192.168.4.0/22, 8.0/22? 330 access lists and 250 nat policies could be part of the slowness depending on what level they are being applied at. Slowness also could be a bottleneck at one of the switches, too much traffic for a switch to handle. These questions are pretty broad and a consulting service may be more beneficial to answering your questions. http://www.dell.com/learn/us/en/04/by-service-type-it-consulting

Hi Josh,
They all are using 192.168.0.0/22 range. is there any way to create VLANs without changing IP addresses of all the hosts

If the IPs overlap you will have conflicts if the networks are able to route, so you will probably need to change IPs.
