Whilst charcoal is (possibly) better than Gas, you can get a damn good BBQ & good flavour with a few tricks.
I alwayd have the lid down on my gas BBQ, whenever possible...ignoring the advice to turn the burners down

OK, you do get loads of flames coming out of the side (adds to the fun) BUT it does allow the smoke to permeate through the meat.
When firing a gas BBQ up, I always put some cheap Asda sausages on first. They drip fat like mad & get flames bursting up.
I also have a bottle of cooking oil, with a hole pierced in the top...& spray it on from time to time.
I never turn the steak or burgers more than once & avoid sticky marinades..it just falls all over the burners anyway.
As for chicken....I soak it in lemon & lime juice for an hour before...just brilliant!
For lighting a coal BBQ, forget those poxy bricks!
Line the base of the BBQ with cardboard, soak it with BBQ lighter fluid (or petrol, turps, meths etc) & throw the coals on top...SIMPLE!...
or mix Potassium Nitrate & Icing sugar & light it!!!
As for bonfires...soda syphons (Co2) are great when they go bang!
