My poor little Moggie has just failed her MOT

. I got a quote from the garage that did the MOT (not a Moggie specialist), but have also got a quote from another reliable trustworthy local sole trader mechanic. She's failed on some 'excessive corrossion' around the nearside and 'offside rear suspension spring mounting prescribed area'- my friend (the local trustworthy chap) has had a good look around and can't see all the problems they've identified ... he has found some bits that need doing (not big jobs) but not to the extent they've picked up. Anyone else had this problem???
Another thing she failed on is that the steering column top bearing is excessively worn (ie there's a bit of play at the top of the steering column). I've had a look on the usual suspects Moggie parts sites, but can't see the parts I think I need for the repairs... Can anyone give me alternative words that I should look for instead of:
Steering column top bearing
Front suspension arm rubbers
Your advice would be greatly received, as I'd like to get her back on the road asap
