hi dirthalr,
welcome to the forum. you picked the perfect place to ask a few questions, this board is full of brilliant people, who will help a guy out.
for servoes, you cant go wrong with hitec 645mgs:

and a radio depending on your budget, can be tricky. the mfu with lights and retractible landing gear will all work with a regular 4 channel radio, the mfu actually works as a speed control, so all your tx inputs are seen by the mfu and it directs the input accordingly ( so when you turn left, it turns the wheels AND makes the turn signals come on)
a 4 channel will save you some $$$$ but it puts a dump trailer that dumps (from the tx) out of the question. and if your like me, as soon as you buy a radio, you'll realize you dont have enough channels! i would get at least a 6 channel, it give you room to play around later.
i run spektrum, and im very pleased with them, great quality, programmable , and easy to find at any hobby store. i live a good distance from any stores as well so having things they all stock is a bonus! you could also go with airtronics, futaba, hitec even has 2.4
ghz radios now.
