나 좀 도와줄래? 좀 도와줄래? 나 좀 도와주라. - Please can you help me a little? without the word "좀" it does not sound native. The word itself means "a little." But it is used as the meaning of "please."

돕다 is a verb for accusative object. Thus, 나에게 is wrong. It should be 나를, if this object is to survive. - 도와줄래? - 도와줄 수 있니? - 도와줄 수 있겠니? It sounds VERY awkward in Korean when you don't omit the "unnecessary" subject and even object. In this case, both should be omitted. You shouldn't think about reasons for omitting them, but the other way around. Try to find VERY GOOD reasons why they shouldn't be instead. Isn't there any, omit them mercilessly.
