How many bytes can be written between flushes when writing data to the SD card? Can/will the buffer flush itself when it gets full?

FLUSH do not need additional buffer.
AVR-DOS write the Data to the card, if the Data sector with 512 Bytes is full. IF you close the file, AVR-DOS writes the data sector to the card in all condition and update the Dirctory information for the file like size and date/time.

FLUSH only updates all information to the card like CLOSE, but do not really close the file, so you can go on to write data to the file.
