Re: shaft alignment
As mentioned above you cannot do anything until you deal with the bent strut.
However, installing the strut correctly is not something you should attempt yourself. It isn't just a case of rebolting it in place. It must be perfectly placed (shimmed or holes redrilled if necessary) or you will never be able to align the shaft properly. I highly recommend you have a yard professional do that job.
The alignment itself is not difficult as long as the engine mount bolts are free and easily turned. I can't remember the exact number of deviation from perfect that is acceptable, but it is in the thousandths, so be prepared for some very tedious work with a feeler gauge.
