I believe there are plenty of LYNans are pharmacist, including me

Government hospital. Pharmacy law stated that you have to undergo 1 year of Provisional Registered Pharmacist (PRP) in government hospital + a 3 years compulsory services after you graduated and wanted to work as pharmacist in Malaysia. So you don't have to worry hunting for job after graduated.
Not really. There are many other 4 major fields you can involved, hospitals, retail/community, industrial and education. On the hand, research is probably more important for pharmacist lecturers. You will need your research to boost your reputation and get your title status in the university. Before you can become a pharmacist lecturer, you have to be at least a Masters degree holder or better a phD holder.
You can try to google out the difference to have a clearer image.
Good luck on your study
