A Q about fixing my mg tf. Wondering how much it is going to be to fix....?

I need to fix my handbrake, brakes are squeaking slightly and I had a squeak that sounded like the shock absorber, but that squeak has recently stopped, but the problem may still be there. So these potential problems plus the M.O.T itself is �50 and tax is due which is �115. So what you guys think the total cst might be :)?
