Study to show yourself approved by God. Seek God about deliverance.
Deliverance is a constant learning process.
Satan has spent thousands of years weaving a very complicated system to trap you and take you to Hell or cause you to live a miserable Christian life here on earth. Get Experience - start casting out demons and get involved. Study Bible - use a concordance and study Gospels mainly. Fast and pray - seek the Lord about your problems. Study deliverance books - learn as much as you can.
