The premium labs you've purchased access to gives you access to ACTUAL equipment, not GNS3 or packet tracer. It's a full lab environment setup for you to use so you should have access to actual routers and switches for each lab that is presented.
The key to usage and preparation for the exam is SPEED and ACCURACY. Make sure you not only practice configuration commands but also the different SHOW commands will be important for the CCENT exam. You must be able to exam what is displayed to help you when your configuration is not working. Make sure that you can subnet quickly and accurately. Practice your subnets especially the /12, /16, /27, and /29 very well.
