configuration of a new computer

I'm trying to follow instructions in README.md of /nophead/Marlin on github.

the first problem is that v22 of arduino is no longer supported , which version should i use?
if i try to run 1.0.1 that came with the printer windows 8.1 just shows the flash screen and nothing happens .

I run it with 1.0.6 after adding the directories in place (Melzi, Sanguino and tools) and then i can select the right board.

comparing my old config to the new the values of default_k[pid] have changed

I the new file shows 25.05 2.3 and 68.15 ,
in the file file I've had the values are 34.19,2.47 and 118.19

I do not remember changing them . which do i use?

ALSO

it is trying to upload to COM1 with "Serial port" grayed out.
how do i change that ??

The PID values changed when I added the silicone tape to the hot end, so use the later values if you have that. Or to get the optimum use the auto tune in Marlin and generate your own.

If the COM port does not appear when you plug in the printer you probably need to install a driver for the FTDI chip. That comes with Arduino.

Thanks
the solution to the COM port was to go to the control panel and remove all of them.

I a not familiar with marlin auto tune, assuming it is [reprap.org]

you had sent me a replacement hot head when the original came apart so i might have changed it then .

I now see that the old file i had says J-Head Mark IV-B
and the new file says J-Head Mark V-B .
(how do I know which one i have?)

thanks

HMMM, new problem
yesterday i was able to change configuration.h and upload.
today
"can't find programmer id arduino"

which programmer should i use (it was set to AVR ISP mkII)

not sure if yesterday was the same, but i did not change it

ok solved it,

the problem was that after downloading arduino 1.0.6 , and putting the sanguino and melzi directories into hardware i also (and shouldn't have) over wrote avrdude

All the kits after the first 5 used at a workshop in Sheffield have J-Head Mark V-B, so that is what you have.
