Answer

"我去过公园了""去过公园了" and "去过了" are correct, but the first one is the best because it contains subject and object as well as the place, just like the sentence (in English) you give.

Answer

You can say：
我没去公园。
我没去。
没去。

Answer

Yes,that's right.

"I haven't been to the park."you can say 我还没有去过公园。
