Just to qualify on the trains - I think you may be able to (and need to at busy times!) book on some of the longer distance Scotrail services, but not in the central belt area, you can't book on the Edinburgh-Glasgow trains, or the trains that end in Stirling, Dunblane, North Berwick, or any of the SPT trains.
Oban trains certainly used to need booking. The Scotrail website has all the detail.
If you find you need to book for a route, go to http://www.eastcoast.co.uk/, where, after choosing your preferred train, you can select to add bikes to your booking. If there are spaces left, you will be prompted to pay for the ticket, if there are insufficient spaces, you can go back and try your luck with a different train. If there is no option to book a bike space (say for Edinburgh-Glasgow), you won't be able to book a space. But these are frequent trains and not normally a problem. (You will need to tick "reserve a seat" to be able to book bikes on). You can book for all trains in the country on EastCoast, or you can book through the phone booking system, for tickets and bike spaces at the same time. Beware that the Inverness trains are often fully booked in advance, due to the ridiculously small number of bike spaces.
Enjoy Bute! (it was HJ's write-up, not mine, but any photos of him (and some others, too) were definitely taken by me ;-)
