Infinitives

How do you make sentences like that with the conjugated verb plus the infinitive in Japanese?

How does one say...
I want to go to school.
I can go to school.
I have to go to school.
I like to go to school.
I want to go to the store, but I have no money.

Is this correct?
Dionyusosu no chikara de, henshin yo!
By the power of Dionysus, transform!

Thanks a lot!

How does one say...
I want to go to school. - がっこうへ行きたい
I can go to school. がっこうへ行ける
I have to go to school. がっこうへ行かなければならない （or contracted to: いかなっきゃ）
I like to go to school. がっこうへ行くのは好き
I want to go to the store, but I have no money.お店へ行きたいけどお金がない。

Yeah, sounds good to me, but Dionysus would probably sound like daionaishisu (ダイオナイシス) or maybe not. Probably need to ask someone that's read Greek Mythology in Japanese. I barely read it in English.

がっこうへ行くのは好き

I think I've seen this before, but I'm confused a bit. What's the difference between 「がっこうへ行くのは好き」 and 「がっこうへ行くのが好き」 ? And would 学校に sound a bit better? Gahhhh all these interchangeable particles~!

(Sorry to have butted in)

Errr.... either are fine really. You can consult the は vs が threads to know the differences... probably not worth getting into it here (and I'm not really a good person to ask either) :|

I guess for simplicity's sake, が is probably better.
