I've got mine to the point of powering on and your list is a lot different what I just used.
Were is the M10 theaded used?@ I just used M8 and M5 threaded.
The LM8UU's should only be 10, 3 for Y, 3 for X and 4 for Z.
I presume the 608ZZ are for the extruder, but a standard gregs only uses 3.
I can't see why you'd need 4 endstops, one per axis (3 in total) and if you want to add auto leveling just reuse the Z endstop.
Grub nuts have a small hole for use with a hex key, if you just cut a bolt down it would be a little tricky to work with and near impossible to get out. You could use a small M3 bolt, but it doesn't look as tidy.
Some worth watching out for is the wiki shows wrong lengths for the Y axis for the boxed version, make sure you use the github values it will save a lot of hassle.

I see that the fan on the extruder is pointed on the printing head, the porpuse of this fan is to cool the head or the print?
In other printers it was pointed in 45 degree angle to cool the print.

It is to cool the print, the cowl that is on each fan directs the flow to where I want it. The extruder has it's own fan to cool the hotend at the top. The fans follow the work piece as it is being printed, so for a very tall piece the fans work well as they are always being directed at the newly printed section.

The fan on the extruder is to cool the upper part of the hot end that is not supposed to be colder.
The fans on the sides to cool the print.
thats correct?
