I have a Toyo 45A with rotating back and like it very much. I suggest 120 (or 125) and 210 mm lenses as the 1st 2 you get. In the 120 mm range, consider a Schneider Angulon (not Super Angulon) as a nice, compact wide angle lens. I have a 90 mm Angulon and it performs very nicely--but doesn't allow much in the way of camera movements as its image circle is limited. The Super Angulons are larger, more elements, heavier, and can limit camera movements (because of their size inside the bellows) on the Toyo, though camera movements with a wide angle are not usually very extreme.
If you want closer to a "normal" lens, 180mm is probably better than 150mm, as you'll get a much larger image circle for camera movements.
I think the 45A can focus a 300 mm lens at infinity, but can't get super close.
You don't need to change the bellows for the lenses that this camera can accommodate--the limit for focal length is the length of the extension of the focusing bed, For really short lenses, you'd probably want to use a recessed lens board, though they are a pain to use.
