Bianchi Monza 2008-2009 Bottom Bracket information required please

Hello there:
Anyone could please let me know the bottom bracket required for a Bianchi Monza 2008-2009?
The main disk that engages the chain states "104/64 mm BCD " please see the pics.
Also, the best tool to remove this part? any directions how to do it?
Sorry for my ignorance.
God Bless

Would first familiarize yourself with bike parts & their terminology Park Tool Co. » ParkTool Blog the 'main disk' is the crank, the 104/64mm BCD has nothing to do with the BB.

The Park link will help you ID the BB types, and tools needed.

according to bikepedia
the monza is a middle of the line hybrid
and so
almost definitely has a standard english threaded bottom bracket shell
which is a very common standard

all you need to know is the length of the spindle
in millimetres
and to confirm that the bb shell
meaning the lower part of the frame through which the bottom bracket passes
is 68mm wide
as the vast majority of english road and hybrid bbs are

for tools
you will need a tool to remove the crank bolts
probably an 8mm allen key
and a crank puller
and probably a bottom bracket spline tool

once you get the bb out
you measure the spindle and buy a replacement of similar length

'08~'09, Recent enough its probably Asian contract Factory sourced, so British type BB thread .. Rt side is LH thread.

the spindle length depends on what crankset was fitted .. BCD is about the Chainrings used ..
