I already have a apple ID for my iphone5. And recently I have purchased a new mac book pro.
My questions are that
1: Should I use a existing apple ID or create a new one?
2: If using my existing apple ID, then will there be any issue at later stages?
3: How will I be able to share the data between my existing iphone5 & new mac book?
4: Or will it be better to create a new apple ID for my newly purchase mac book pro?
Please suggest?

Use the existing Apple ID, so you can sync your data between your phone and your Mac.
No.
iCloud does the job for you. Both your iPhone and your Mac should have asked you to enable it during their first setup. See -> http://www.apple.com/icloud/setup/
You do not have to create a new Apple ID for your MacBook Pro. If you do that, you may have problems syncing your purchases.
