The Lt-40 ARF from Sig is an excellent choice for a first trainer. It's big enough to see easily, and it flies great. You can get one for about $135. It's a bit more expensive than some other trainers, but I promise you- you won't be sorry.

As others have said, stay away from the MDS motors for a first time trainer. I like MDS motors. I have two of them and they run good. But, they are a little difficult to tune and they take some time to break in properly- untill they break in- they are a bit of a pain in the rear.

Get the Thunder Tiger engine or even an OS if you can afford it. You can get an OS 46 FX Max for about $110. The OS engine usually run great within a short breakin time and the 46FX will have PLENTY of power for your next plane. The Thunder Tgier Pro 46 is an excellent engine as well. They take a little bit of breaking in, but they run good for years, and they are reasonably priced.

I'd get an engine with bearings, instead of a bushing engine. The bearing engine will last longer and it will produce more horsepower.

As for radios- it's a tough call. Some would say to get a computer radio- others would advise the simple 4-channel radio with no bells and whistles.

The advantages and disadvantages of radios:

Computer radio is much more flexible and adaptable to more and different planes.
Computer radio is a bit complicated to use and can be overwhelming to the newbie.
Basic 4-channel radio is user-friendly and simple.
Basic 4-channel is limited to one plane usually.

If you get a computer radio that can handle 2 or more planes in the radio memory- then you won't need a new radio for every plane. After you solo and need a new plane- you just buy a "flight pack". A flight plack is 4 servos, a battery, a reciever, and a switch. You just buy the flight pack for about $125 and you have all the electronic stuff you need for a new plane. You don't have to go through the expense of buyng a new radio too.

Computer radios are more expensive.

As others have suggested, go to the local flying club and see what they are using for radios. Your gonna need an instructor and you should probably start out with the same radio brand as the instructor. That will make it easy to get you hooked up to a buddy box and start flying right away.

Different people are going to have different opinions about what radio to use. Listen to all the information and get what works best for you.

Good luck and let us know what you decide to get for all your stuff. Welcome to model airplanes and RCU.
