Play in the steering could be a few things. First the front wheel bearings should be examined for looseness and rougness. The tie rodsends should be examined for play the idler arm should be checked for upand down movement. The steering gear on thes cars is adjustable to eliminate some play in the box.
The pulling on acceleration is probably wear in the rear end links.
