When there is one or two balls being spotted you should usually always rack them immediately behind the 1 Ball. The two balls behind the 1 are the least likely to be made on a normal 9 Ball break. You also want to be sure do this receiving the spot as well as when you are giving it, as you don't want your opponent making the spot balls on the break and denying you a shot at them. ( unless you have specified the spot balls must be called or are spotted up if made on the break etc.)
Another little trick that is useful if you are giving up a spot in 9 Ball is, if the table it laying right, make the spot ball from a push-out even if you have an open shot at the 1 ball. This is perfectly legal unless your opponent was smart enough to specify otherwise when you negotiated the spot. (You can always choose to push out even if you can see the 1 ball.)
If you are racking for yourself and receiving a spot put the spot ball(s) in the wing ball position (Outside balls of the third row). However if your opponent is good enough to be spotting you balls they are likely to be smart enough to not let you rack for yourself.
2 great 9 Ball books with detailed chapters on breaking are "Play Your Best 9 Ball" (Full of excellent real-life examples of gameplay) and "Upscale 9 Ball" (Very dry but some really detailed research.)
