Answer

Not bad, but better to say something like:

If I finish my homework early, I'll go, but if it takes me a while then I’m afraid I can’t.

Though simply saying - "If I finish my homework early, I'll go” - is actually sufficient. The additional explanation isn’t needed, but it does make it more polite.

Answer

That is correct.  You could also say “If I finish my homework ON TIME, I will go.”
