So I'm doing genki workbook. Exercise is to write custom request with -てください。

I was wondering about combining　 −てください for requests with -て forms for joinging verbs together. For example, I want to say "Please bring my book tomorrow and return it to me". What is more correct - to connect "bring" and "return" using -て and then form single request in the end, like

明日、私の本を持ってきて、私に返してください。

Or each part should be marked as request.
明日、私の本を持ってきてください。そして私に返してください。

And in this case can "hon" be marked with topic marker ha instead of wo?
