That's because Jack Stamford is a paintballer! Every weekend, Jack travels to a large building, field or wood to take part in a game of paintball. He's part of a team and they try to beat members of the other team. Players take roles. One week he's a spy and the next he's a 'Tomb Raider adventurer. Games can last from two hours to two days!

Don't stop to believe: to believe- инфинитив (глагол в неопределенной форме спряжения), и переводится дословно: не прекращай верить!
Don't stop believing: believing- отглагольное существительное- имя действия. Дословно бы переводилось: не прекращай верение. Но, поскольку такой части речи (и слова) в русском языке нет, переводят так же, как и вариант с инфинитивом.
Не путать с герундием believing- веря, верящий, употребляемым как причастие и для образования времен Continuous Tense.
   
После want следует употреблять инфинитив.

Глагол  to have может быть смысловым , либо вс
Как смысловой "иметь" он ничем не отличается, по употреблению, от любого другого глагола.
Как вс используется для образования времен Perfect Tense. При этом он спрягается, а за ним следует 3-я форма спряжения смыслового глагола. Perfect Tense означает уже совершенное, на подразумеваемый момент, действие.
Примеры: 
I have done it- Я это сделал (на момент когда это говорится).
I had it done at yesterday noon- Ко вчерашнему полудню, это уже было мной сделано.
I will have it done at tomorrow noon- К завтрашнему полудню, я это сделаю.

Кроме того, существует конструкция to have to, являющаяся синонимом модального глагола  must.
I have to go- Я должен идти.
