Answer 1

old values and new
values are to be inserted into the backup table, butwell you have only one insert there, inserting old values with a new id (which is ok if you don't update the id column, but I don't think that :new is available for deleting ops); you should have two inserts:
insert into
phquotes_audit(cprc_new,suppcode,itemcode,cprc_old,negodt,validdt,userid,TRANDATE) values (:old.cprc,:old.suppcode,:old.itemcode,:old.cprc,:old.negodt,:old.validdt,:old.userid,SYSDATE);
if (updating) then
insert into phquotes_audit(cprc_new,suppcode,itemcode,cprc_old,negodt,validdt,userid,TRANDATE) values (:new.cprc,:new.suppcode,:new.itemcode,:new.cprc,:new.negodt,:new.validdt,:new.userid,SYSDATE);
end if;
