As for BB, I assumed it would be an old type with weird crank mounting so my intention was to replace with a square axle BB that would allow for more options but maybe I got this wrong.
700c is sometimes also referred to as 28", you were probably thinking of 27" wheels which are actually larger in diameter than 700c
Your crank appears to be a very common square taper type. The bottom bracket may or may not be a cartridge type. if it is a cup and cone type it will need to be serviced
