1 week in Indonesia, Arriving from Georgetown, Penang

Hi all, looking for advice/criticisms from travelers who are familiar with the trail. My friend and I are first time travelers to Indonesia and are hoping to fit in two areas while we're there. We will be arriving from Georgetown, previously making stops in Koh Tao and Koh Phaghnan. In indonesia we were hoping to cross into Medan and visit Bukit Lawang...estimating 3 days here. From there the plan was to head to Bali, spending the bulk of our time set up in Ubud, thinking 4 days. What is the best way to get between the two places? and does this seem too rushed? After Bali we are heading to The Phillipines for another week, most likely set up on Cebu with days visits to Dumaguete and Apo island. Any suggestions welcome, thanks for reading!
