The biggest risk is you try to do too much too soon.
Break your task down into separate, smaller, distinct tasks.
- Make a script that just retrieves emails
- One that gets tweets
- One that gets sms (you may need some hardware to do this)
- For each of these, just print the output to the screen
- Then work out how to do your ticker - e.g. have you got a monitor/display you'd like to use? If so, get used to writing code for it
- Only once your comfortable with all of the above should you start pulling it all together
For the first 3 I suspect there will be plenty of python code examples to get you started. If you get stuck, post some code here and people will help out.
Good luck!
