I have noticed that you can only pass 16 parameters to a function, I was
therefore wondering how you can do atomic inserts (such as the function
below but with more params) using pl/pgsql if you can't pass complex data
types. Is this something that transactions are not used for or is it best
done as two seperate calls in my perl scripts?

You must to use two quotes:
SELECT nextval(''client_seq'') INTO id;
