Nice work Andy, looking at your snapped off stud brings back recent memories of me having to do many repairs to my casings and cylinder head, just think of the cost if you had too pay someone to do it, as for changing your tyres i would recomend having this done in the tyre center, but if you do it yourself buy yourself some rim protecters, and before you start trying to lever tyre off pop both tyre beads to the center , i use a g clamp sometimes as this helps
