How much prep work has been done in and around Euston so far? A little or none?
The most obvious thing is that Cardington Street has been walled off just north of the entrance near Platform 17 and other buildings nearby are boarded up. There was no visible demolition last time I was there (last week). There have been enabling works going on over the past year or so to move various Network Rail equipment out of the HS2 footprint on the west side, which becomes a full-blown HS2 construction site later this year including platforms 17 and 18.How much prep work has been done in and around Euston so far?

Ground investigation probably.
Engineers working on Britain’s new high speed railway have discovered an ancient, sub-tropical coastline dating back 56 million years. The rare discovery was made at a site in Ruislip when HS2’s ground investigation team unearthed a previously unknown material, located up to 33 metres below the surface.
The layer of black clay, which HS2 Ltd has named the ‘Ruislip Bed,’ is thought to have been formed from densely wooded marshes on the edge of a sub-tropical sea. HS2 Ltd made the surprising find while investigating ground conditions in the area, prior to the construction of the Northolt Tunnel – a 14km tunnel which will run from West Ruislip to Old Oak Common.
HS2 has been investigating the ground at around 8,000 locations along the first phase of HS2, from London to the West Midlands.
The following link is a register of street works in Camden. If one "plays around" with the data a bit, for example, filter "responsible company" to HS2, sort by date and so forth, one can glean some insight into when streets are due to be stopped up, hoardings erected and so forth...

You can even download it (to Excel, XML, etc) if you are so minded.
Superb work
Sorry can you re-phrase this question. I don't understand.What do you envisage the changes in spec from HS2 to classic trains on the network? I know its a generic question but I am currently looking into obtaining as much information as I can, on an assignment for uni. Much appreciated if you could help
As @jyte says the question isn't overly clear. If you are asking about the difference between the HS2 stock (classic compatible) and a generic other high speed train in the UK, the main differences that come to mind include an increase in installed power, signalling systems specifically for running on the High speed line (TVM430 will be most likely unless it's been announced differently) which will be supplemented by traditional UK systems such as AWS and TPWS on the 'classic compatible' sets, a different pantograph design optimised to work with the LGV style OLE (compare the pantographs of a 395 designed for HS1, compared to a more generic Brecknell-Willis High Speed Pantograph as used on most other UK stock), and no doubt some other differences.

I imagine the 395 uses a different design because unlike the e300 (in the form of the NoL sets) they're never expected to operate on any other OHLE?The Brecknell-Willis High Speed Pantograph was used on the Eurostar e300, which was designed for LGV Nord and HS1

Well, there was the project specification I referred to. I know that's even older, but are you positively saying that ballasted track has been explicitly written out of the civils contracts?
"90. The track it sits on is of a German design. The picture is actually taken in Korea. Now, I’ve chosen this picture not for any other reason I think, than to make a second point which is, if you look at the track, it is a continuous concrete slab. Conventional railways are built on concrete sleepers, but in some parts of the world, and for Phase 2A of high speed, like Phase One, our track is based on a continuous concrete slab. It is actually pre-cast and set in on a foundation. And the reason for that is that this is a very heavily used railway. In Phase Two, 12 trains an hour running at high speed is, in engineering terms, quite challenging. So, a continuous concrete slab enables us to run a safe service, but with minimal maintenance"
