user61712: I am a noob in the Arduino world and have only started reading about it. I have zero experience with Arduino some suggestions to increase my level will also be highly appreciated. But I have a lot of ideas, I want to work on.
I want to measure the velocity and noise levels with the GPS coordinates of a moving vehicle and send it to my phone using gsm or wifi.
Should I include a small LCD also? again suggestions will be highly appreciated.

user31105: It depends.
If you are a beginner, do it in steps:

Get an Arduino Uno
Get a feeling for MCUs connecting a LED and resistor.
Connect the buzzer and get it working.
Disconnect it, connect the display and get it working.
Same for one sensor.
Than try multiple sensors.
Than play with the WIFI module.
Than combine everything.

The key is to split up your (for a beginner) big project into smaller easier to handle projects.
If you want to add an LCD, depends fully on YOUR requirements; we don't know exactly what you want. If you send all data via WIFI in principle the receiver can display it, but maybe you have a good reason to display it on a display.
