ATC is full time and professional there so you won't need to join overhead. You'll be cleared to join directly into the relevant circuit of the day. As for approach, they are usually band boxed with tower so you'll probably only speak to one person.
If approaching from the East beware of turbulence over the hills, especially with Easterly winds which leave the lee area quite rough. Warton radar is available for the usual services in Class G airspace.
The field is large with the prevailing wind Westerly. Expect to use 28 unless the wind is strong and favouring 31. Even then both can be in use simultaneously. One thing to note is that if landing on 28 you will be expected to exit quite far up the runway with aircraft holding to enter at 'Echo'. Don't make yourself unpopular by landing on the numbers and then blocking the runway whilst you trundle up the other end. Parking is on the North apron with fuel nearby. Beware it's traditionally been one of the most expensive outlets in the UK.
Landing fees are also a bit high. I pay £36 for my PA28 when visiting my maintenance company. That said, there are 'training rates' that you might explore.
Otherwise a very friendly airport with easy transit via bus, tram or taxi into the local area.
