In this case, yes. It would be optimal to switch between killing popcorn, hitting the boss and using burndayraz on him. This way every fireball takes down 2 DP and if you use the bear mace, every attack takes down 3 DP (attack, knockback, magic shield).
One attack and one fireball are worth 5 DP, so the DP are fading away faster than with every other class. As most of the damage is excess, you can even use some tiles to heal yourself inbetween without that being a problem as long as you manage to get him down to 0 with one hit/fireball to clear a DP. The main point about popcorn, though, is to have enough to easily reach a new level while fighting the boss, as to use the free healing of HP and mana. The healing and extra mp of the sorcerer helps in lasting even longer.
If you're adamant about using the berserker, you can use wurhgarble to have a similiar burning effect as burndayraz on hit, also helping you lowering the DP by killing popcorn (even without the need of positioning the enemy).
As for preps, I'd suggest either an amulet of yendor (which helps you lvl up fast at the beginning - I find this a very good prep for inexperienced players as it basically gives you alot room for errors in the early game, if you're having trouble with that or an full heal during the boss fight) or the platemail, which is best in an endurance fight against a low damage boss.
In other boss fights, igniting the burning is generally a bad idea. The damage dealt is low and the burning effect increases every damage you do to a boss (it works like a temporary corrosion), so there is not much incentive to lose it.
Also, it hinders the enemies regeneration which helps your regen fighting alot.
