Sounds like possible interference on the endstop wires from the motor wires.
Make sure wires frome each endstop are twisted, and also each motor wires are twisted.
Try to route enstop wires away from motor wires.
In firmware, there will likely be an option to 'only check endstops when homing', this will elliminate any crosstalk.

Ok.
Using RH,send a
M92 Z400
then send a
M500
This will store the new value into the eeprom (if eeprom is enabled in your firmware).

The prussa calculator does not take in to account the 4 starts, therefor gives you a result of 1600,which is fine if you do have a 'single start' lead screw(look at the end of the thread, see how many thread ends it has).
If it has 4 thread ends, then you need Z-steps/mm = 400
AS i said befor, repetier host has a eeprom editor in the config menu tab, you can change the value in eeprom from there.

Its a prity sure bet the GT2560 will be set at 1/16th microsteping.
The important part of the leadscrews is
Lead of thread: approx. 8mm which leads me to believe they are 2mm spacing with 4 lead starts
so your steps/mm will come out at 400
this can be edited directly into the eeprom via repetier hosts eeprom editor

If you mean a part cooling fan, this is usually connected to the 2nd extruder heater output(if your board has one). and is controlled via the slicer software

This sounds like the usual max z feedrate being set too high in the configuration.h in marlin default firmware
ie
#define DEFAULT_MAX_FEEDRATE { 300, 300, 5, 25 }
try reduceing the 5 to a 2 and recompiling firmware

The auto level data is stored in the eeprom.
To clarify my previous statement,
If you do a
G29 ; probe bed level
G28 ; home all axis
G29 will perform the bed levelling ans store the results in the eeprom
G28 will home Z and this will reset the bed levelling data
so use
G29
G28 X0 Y0 ;home X Y
G1 Z0 F5000 ; move Z to 0

Repetier host has a built in eeprom editor, you can change the Zsteps/mm and Z max feedrate via that editor

Your best option is probably to edit pins.h and swap the pins used by Zmin/Zmax

Try putting a G90 between the G28 and G1 Z5 F5000 lines, clutching at straws but i cant see anything else in the G code that could have any effect.

Are you saying the nozzle is above the bed while doing the 1st layer of the print, or just that it is above the bed while heating up ?

In config_adv.h there is an option to 'only check endstops while homing'
un-comment this
// If you want endstops to stay on (by default) even when not homing
// enable this option. Override at any time with M120, M121.
//#define ENDSTOPS_ALWAYS_ON_DEFAULT

If eeprom is enabled in firmware you could use a host like repetier or matter control to edit these values

2mm sensing is very small,this will be much less when sensing alluminium.
carefull, 12volts on the signal wire will kill the processor i/p pin if you dont protect it.
remove the // on this line to enable all pullups
// #define ENDSTOPPULLUPS // Comment this out (using // at the start of the line) to disable the endstop pullup resistors

The marlin default Z speed of 4*60 is usually too fast for the Z axis in most cases. I would try 2*60 and work up from there.#

What controller board does the printer have ?
What display does it have (reprap full graphic or alpha numeric)
Bed thermistor and hotend thermistor are usually 100K ohm types
Other problems sound more a configuration.h is not configured correctly

In features section of repetier fw tool, when you enable z probing box and servo support box it then gives you the option (about half way down features page) to enter the
probe start script and
probe finished script

yep, repetier uses G32 S2 (S2 save data to eeprom) for bi linear levelling and G33 for mesh levelling.

Repetier FM uses M340
Try M340 P0 S1000
or M340 P0 S2000
if these do not work then you probably have the wrong pin selected.

What processor chip is on your board, some (or all) sanguino/melzi only have 128k memory as apposed to 256k so memory is rather small.
You may need to disable parts of the firmware you don't need to get it to fit,

Not really, i would say that Z is not moving enough to clear the previous layers that are printed.
This could be for a few reasons,
Calibrate the Z steps, make sure Z moves 100mm when told to move 100mm
Too much palstic being extruded, calibrate the extruder steps

QuoteI switched the x motor and that worked but my endstop was in the other direction
just reverse the homing direction in config.h ie. -1 to 1
