Firstly connect to TomtomHome and have it update your One to version 7.903 minimally.
Then patch the navcore (the application). Info for this can be found in the Tomtom Tutorials subforum here.
Next get yourself the 850.2820 map or if it is already out there, the 855.2883 or 855.2931 map. You also need the meta code for it, usually in the file meta.txt.
Then patch the map with the same tools that you patched the navcore with. Again, read a few topics in the tutorials subforum.
Bootloader upgrade is only necessary if you plan on using SDHC cards larger than 2 GB. In that case, start with bootloader 5.5022 as you don't really need any newer version and it is quite difficult to go back a version if the latest one misbehaves. 5.5130 for exemple is notorious for slow USB transfer.
