I reckon you need to visit a reputable bicycle repairer, mate! The tapping thing is all about tools ... and ditto getting the sheared off bolt. What is an 'easy out'? I guess a left threaded bit is specially for going easy on tough steel drilling jobs? I've never heard of these.
As for the distance between the chainstay bridge and where you want the mudguard to end, You might be able to try to fashion an alternative to what you refer to a the P clip, or somehow rebend it? If you reverse it, so the open side faces upwards, you can bend them right outwards, to take up the gap ... It's hard to describe but if you;re interested I can show you how I got 'round this with my path frame, I don;t have a photo of that detail but i could take one. It's pretty simple.
Or, you could try to make a kind of bolt/spacer arrangement, and then attatch the clip to that, rather than direcly to the mudguard... it's be cool if the spacers were rubber or plastic to stop rattles. EDIT ooh just looked at the Spring Thing ... cool idea.
