Get a descent Hakko soldering station in the long term. The cheap irons are serviceable but the tips don’t last and tend to total out the iron - they’re serviceable as a learning tools but do not rely on them forever.
That said if you insist on a cheap iron, buy 2 and find one with 2 tips (1 attached/1 extra in box), so you aren’t stuck when the tip burns up within a few uses. After you use the tips up or go through both, the tips can be kept around if you like or discarded. I don't like these irons, but Walmart sells a disposable iron with solder and an extra tip and solder for $10. Don’t do this long term - it will cost you more then a good iron!
As far as buying solder, the Radio Shack solder is excellent if you can buy it, especially 60/40. I have a few rolls I got when the store here closed since I may not be able to find another one easily again. Stick with a few good brands, but keep a good quality backup on your mind just in case.
