As for Uni, it depends on what you want to do. A degree is not the be all and end all unless you get one in a vocational subject that has a high demand. Too many people come out with Mickey Mouse degrees that have no specialism, or they one that is oversupplied in the job market (IT is one in particular).
If you don't have any A levels and you want to go to University, then I can recommend doing an Access Course at college. Many are specific to vocational degrees (Teaching, Nursing, Social Work, Science etc.) and will not only get you into university but will also make the first year a doddle. I did one and am now in the final 5 months of my Nursing degree!
