1. Which version do I need to have installed
2. What is the upgrade path to that version (i.e, is there a stepped upgrade path or do I just go straight to that version)
3. Is there any benefit in going higher than the stated minimum version and if so best way to do so (again in steps or just from my version to latest)
4. best place to get FW upgrades from and I assume I need to burn these to a particular type of DVD? If so which?

2860 is a rare version of MMI for A8s; most cars from that era seem to have 2120 or 3460. The 3460 update is the first I'm aware that
included an update to the AMI firmware [to 0170] which implies it must also support AMI. But it's possible that AMI support was introduced earlier than that, so your 2860 may well work.
The last version of 2G MMI was 5570 which came as part of a 3CD set containing 5150, 5570 and Bluetooth phone ECU updates [BTA and HandyVorb2]. Amongst other things, 5150 will update the AMI to level 0850, if it isn't already at that level.
There are no known issues going from MMI 0890 onwards direct to 5150 and it's probably possible to go straight to 5570. However, since the update set contains both CDs, you might like to consider 5150 then 5570. [I went from 0890 to 5150 and then 5570].
If you have the original 'SIM in the arm' phone ECU, that should already be at 0770 so no further updates will take place. If you have a BlueTooth phone ECU, there are no updates on the 5155/5570 CDs; they're all on the BT Phone update CD. From MMI 2860 there will be major updates to 1130 [HandyVorb2] or 1120 [BTA].
I would buy the 'original' 3CD set for the least risk. Not sure if they are still available from Audi dealers; you may need to ebuy them! Someone else on this forum may well advise ...
