Newbie. Please Help

To gain full use of a zedboard you'll need to learn a few things, but some of those these depend on how you are going to use it and what parts of the design you'll be responsible for.  The big question is whether or not you are going to put an OS on it or or just run a single binary application for the project.

Case I: single binary application
You have two tool flow paths you can use 1) Vivado and XSDK or  2) ISE and XSDK.
Vivado or ISE are used to configure the microprocess system and the FPGA core.  ISE is really a couple of tools: PlanAhead and XPS.  In Xilinx there's also the lower level command-line tools that are actually the backend's to the GUI tools. 
XSDK is an Eclipse based C programming IDE to write the application.
--
Case II: embedded OS to run application
Again you also have two common OS options here.  One is FreeRTOS and the other is Linux.  FreeRTOS is a free real-time OS than has support for thing like LWIP (TCP/IP library) used if you want your app. to communicate over Ethernet using normal POSIX type library calls.  FreeRTOS apps can be developed in the XSDK environment.

Linux requires additional skills, but can make building applications much easier as the apps. can be written as you would any Linux application. The skills you would need to talk to your own custom FPGA hardware are:
- Embedded Linux
- U-boot  OS bootloader
- Linux Device Tree
- Linux Device Drivers
- Linux Kernel configuration and building
- use space memory mapped I/O
- Basic linux commands as you will be doing a lot of work in a terminal window so make you you know things like: cat, vi, ls, > | (redirect operators), cd, etc.
--------------
For any of these paths you will also need proficiency in:
- VHDL or Verilog for custom logic
- C programming, in particular pointers, data structures, interrupts, and low level bit maninpulation operations,
- Interfaces: SPI, serial, IIC, etc.
- Basic electronics: logic devices CMOS, TTL signal levels, voltage, current, power
- Basic debugging skills for both hardware and software

Also make sure you go through the tutorials on this site.  They'll give you some great insight into the tool flow.  I would also go to Xilinx's youtube channel and go through a lot of those as well. 

They'll also be a ton of reading.  Become familiar with Xilinx's documentation system.  There are literally dozens of documents related to the Zynq part and the s/w tools and many of them are several hundred pages long.  It will take some effort to learn how to find what you are looking for and to try and keep it all striaght.   It's hard for one person to be proficient in how to build a board with the part, how to design and test the FPGA code, how to write the software, and how to deal with an embedded OS on it.  Usually it's a team effort. If you enjoy learning, it's quite an adventure.

Hope that helps,

John
