Your camera is normally known as the Canon 400D.
Can you explain which menu button you have to press ?

From what you say it sounds as though AF is not working and although this can stop you taking a picture it shouldn't give a busy warning.
I think the first thing you need to do is to reset the camera to factory default setting (clear all custom settings), this can be done in the main menu if the camera mode switch is set to either P, AV, TV or M. Also bearing in mind the age of the camera it would be definitely worth replacing the back-up battery, this can be found in the main battery compartment, Remove the main battery and remove the little slide out container that houses the back-up battery, in the battery compartment on the side nearest the hand grip, replace this with a new CR2016 button cell.
Try all that and let us know what happens.
