Hello flyvirgin.
To begin with well done, welcome and good luck.
Do remember that the radio is the least important part of your duties and of the aircraft.
The less you say the better. Who you are and what you want is sufficient.
There is no requirement to speak to anyone when in uncontrolled airspace and your first call on 121.5 will get you help just as quickly as if you had been in contact with flight info.
They are there for your benefit; you are responsible for the aircraft.
It is also possible to depart and arrive without radio at many GA airfields where radio is the norm.
So relax and enjoy.
