To get encoder ticks, you can connect the encoders to an Arduino, among many other ways. You will find a lot of help to write a script online. One example is: https://github.com/centauri-robotics/...
To connect arduino and ROS via serial communication, checkout: http://wiki.ros.org/rosserial_arduino...
For odometry calculations checkout: http://wiki.ros.org/navigation/Tutori... or
https://github.com/centauri-robotics/...
You can find a lot of relevant help at http://wiki.ros.org/navigation/
In future, try to break down your questions and search for it, a lot of these questions already have good answers
Is it possible to connect the hall sensors directly to a motor controller such as the RoboClaw Driver?

You can publish your data to ROS irrespective of which embedded board do you use. Control the motor get the rpm and publish it into ROS. In case of Arduino have a look at Arduino pacakge. There are plenty of tutorials for that package as well.
