Oh how I wish I'd had a carpet when I was doing mine...... or a garage......
I do, however remember the sense of achievement with every bit that got done - project creep or not, it's nice to know that my car will be solid for the forseable future - and I'm sure you'll find far more than you want to, but at the end, you'll have a really solid car.
As far as the radiator bracket goes, I can't tell from the picture, but it doesn't actually look any worse than most I have seen.
They seem to be somewhat over engineered in the guage of steel used in their making, and although they can get crusty, I have had really good results with a sandblaster and a bit of paint (well, galvanised and then painted, but you know what i mean!).
I've only had to do one minor bit of welding on one I took out, and that was only because a captive nut was knackered - I've never seen one 'holed' or significantly weakened to the state where they can't be easily rectified - remember, it cant be seen, so even my welding doesn't look too bad when it's fitted.
Edit - other posts whilst I was typing! - it looks repairable to me, it's only a steel sleeve (8mm internal diameter) welded onto steel plate - as Andy says, it can be repaired in stainless if you want to.
