sgpnut,
Just a few things to consider -
I noticed that you have only done 2 pretty straightforward Munros and no circuits. If you have other mountaineering experience outside of Scotland this may not too much of a concern, however my worry is your experience navigating and map reading in the hills. Perhaps dip your toe in the water by taking on a nice circuit like the White Mounth (
http://www.walkhighlands.co.uk/cairngorms/white-mounth.shtml). But I would suggest doing this with someone who has experience - if you are new to navigation and suddenly get caught in dense clag (fog) things could go wrong very quickly. Perhaps ask one of the folks on this site if they'd be up for joining you. In fact roping in some people to head up the occasional walk with you this summer will probably help a lot in lifting your spirits - no matter how much you enjoy your own company a friendly and fresh face does us all the world of good
As for actually doing all in one summer - breaking them down into sections with key towns / camping areas acting as a base for each section would be what I'd first consider. Unfortunately access to a car is undoubtedly the only realistic way to connect the Munros. Public transport in this country isn't really up to the job. But getting your hands on a bike can be a real help esp. for the Munros with long tracks to the foot of the main ascent - I've used a bike for this twice now and it really cuts down on time but does mean that the walks you do where the bike is used need to be circular.
It'll be hard to avoid wild camping if you're planning on bagging them all in one summer. Make sure you get the right kit and know your public access rights
and obligations. Other practicalities need to be considered such as knowing your first aid basics. for example.
Read the right books, get the right kit and get in some real experience in the next few pre-summer months AND most of all best of luck mate, whether you do it or not getting out into the Scottish hills is a wonderful experience in and of it's self - enjoy
