Hi Eitan,
Thanks for choosing S32 Design Studio for the development.
If you are not so familiar with Eclipse IDE I'd suggest to use this community as a knowledge base.
There are also many other sources you can benefit from to speed up learning process:
e.g. Erich Styger blog MCUonEclipse ( MCU on Eclipse | Everything on Eclipse, Microcontrollers and Software )
We have some specific learning documents/videos available at main S32 Design Studio community page:

If you want to know more about SDK (drivers, middleware...) please visitS32 SDK community
S32 Design Studio is shipped with many SDK examples (see e.g https://community.nxp.com/message/1023558?commentID=1023558#comment-1023558 ) as well as documentation (c:\NXP\S32DS_ARM_v2018.R1\S32DS\help\pdf\)
Hope it helps.
Stan
