i dont know about the chassis leg mine faile don sills and was quote £100 for new sills on both sides, which aint bad at all, rear wheel bearing are very easy, i have to put 2 new ones on mine approx 30mins with the right tools. hand brake can be adjusted inside the car if you remove the gaitor or under the car, if doing it inside the car just be careful not too tighten it too much as when i started out i tightened it too much on my old corolla gti twin can and snapped it, the driver shaft gaitor isnt a big job really, i got a pair of universal gaitors for £9.20 (at trade) from local parts shop and didnt take too long at all. now i am not a qualified mechanic but i have just took my time on jobs and learnt as i go (with haynes aswell) as im the same cars failed mot, had very little cash so i just decided im not loosing anything with me doing the work as its off the road anyway!!! id think long and hard mate what it means to you. good luck making a decision!!
