Is there any book or guide with MikroTik Labs, something like cisco labs.
Also what would be good and affordable equipment for lab enviroment and testing purposes?

All mikrotik devices sport all ROS features, so for lab use almost any device will allow you to setup labs.

Unlicensed CHR will be limited to 1Mbps, but again, for a Lab this still allows to setup any scenario, and you can get an unlimited temporary license for 60 days. You can run user-manager or dude server on it.

That being said, if want to invest some money, and get used to specific physical hardware differences, my pick would be

• A CCR1009-8G-1S: Allows you to play with hardware switch features, and direct CPU ports. You can run user-manager or dude server on it.
• A CRS to get familiar with switches. Some, like CRS326, can boot either RouterOS or SwOS.
• Second hand RB1100AHx2: this device has been the workhorse of Mikrotik lineup, if you find one second hand is a real value router. Also offers two switch groups and independent, direct to CPU ports. No dude server support.
• Hex (750Gr3) Little mean dual core router, sports IPSec hardware acceleration. With proper optimization this $60 router can push 1Gbps. You can run user-manager or dude server on it.
• For multiple physical routers setup, play with wireless, test CPU loads, etc: mAP, hap lite are really unexpensive routers, allowing you to setup HA setups including wireless with 6, 8 routers for a little investment.

Not that I am aware of. To get trained the best (and only approach) is attending real life certifications.

Have you seen this article about GNS3 and Virtual Labs?
