It's the same. Hoćemo "form" is used more often in my opinion. Be careful with hoćemo. It literally means to want. It would be more grammatically correct if you would say : Hoćemo li pjevati pjesmu?- Shall we sing a song. Hoćemo pjevati pjesmu. We want to sing a song. In everyday speech we often omit that li, if the meaning is understood. For ex.: Hoćemo ići na kavu u tri. It is actually a statement but with proper intonation it can be a question:). You could also say: Hoćemo li zapjevati pjesmu? Shall we sing a song ?-it's not used often. :)

Prestala sam piti instant kavu. is correct. You can also say : Prestala sam pušiti. That is if you have been smoking and you have quit doing that. If you want to say it in one sentence : Prestala sam pušiti i piti instant kavu. Ne pušim. I don't smoke. Ne pijem instant kavu. I don't drink instant coffee.

When you are ordering food at a restaurant Molim Vas is polite way of saying things.... it's something like (onegai) pleas. Because of Vas it is formal, if you would to say Molim te. .....that is more informal way of saying please (it's usually said between friends). Želim = I want or I desire....It's common. Imate li ? ( Da li imate xxxx?)= Do you have xxxxx ? It's formal and common. Rado bih....this one is a bit tricky. You can say that but is sounds archaic and although it is very polite it's too polite in daily speech. This tense is called Aorist ( i think :) ) , so you can look it up. If you can imagine situation in which you play a role of princess this would be tense in which you would speak. Ja bi(h) svinjetinu. or Svinjetinu molim Vas. It's common way to say I would like to have pork.

Kako means How, in what way. Kakav mens what is it like. Kakav je on?= What is he like. What kind of person is he. Kakav je to pas. What kind of dog is it. Kakva je to kuća.
