I'd take it to a reputable alignment shop and
allow them to do an alignment.
If it they are unable to because of worn parts,
they will tell you what needs replaced and from
there you can make an informed decision about
a total overhaul or minor repairs.
There are several threads on here about alignment specs
or just ask and someone will give you advice or,
P.M. me if you wish and I will make a recommendation.
The short answer if all is in good repair and alignment done,
A good set of shocks and tires IMHO.
