If you have been to Angkor Wat, u would think My Son (pronounced "mee song") is a waste of time.
Danang also nothing much. Unless u like to walk along the Bach Dang promenade and people watch at sunset.

Spend more time at Hoian and Hue (pronounced "hoo-way").

No itin required. If u wanna skip Danang entirely, when u land at the airport just take a taxi to Hoian (20-30mins). U can ask the taxi driver how much first. Around 350-400K vnd is fair price. If u need an MPV, ask for a 7-seater xe bay cho (pronounced: say bai chor). It VN, its always a std practice to tip... dun be so stingy to pay the exact amount. For eg if its 360... just pay 400.
At Hoian, relax, walk around and pop into those travel agencies to arrange your bus tours to Hue. Recommended ones are Sinh Tourist.
Maybe u can share your list here and I can offer my comment.

A bit hard to answer your question. But all the times I have visited the area, I skipped My Son because it is just a bunch of destroyed ruins and also I have visited Angkor. But that's just me.

Bà Nà Hills Fantasy Park - some ppl like it, some ppl hate it. I have always skipped.
Marble Mountains - Ngũ Hành Sơn - can visit at least once.
Son Tra peninsula - not sure what this is.
Ban Co peak - not heard of this.
Bach Dang street – night - Yes, can walk along the promenade at sunset. Great for ppl watching,
Chùa Linh Ứng – Lady buddha - Uhm not sure what's this.

Hoi An ancient city - A definite YES. I would stay at least 2-3 nights.
My Son Sanctuary - See my other answer to the lady.
An Bang beach - This is within cycling distance frm Hoi An.
Night market in ancient city - If u mean the stalls near the bridge, they are open every night but u can cover it in 10-15mins. Very short stretch.

ALL BELOW, YES, ITS COVERED BY YOUR LOCAL TOUR. USUALLY COVERED IN ONE DAY. HUE IS A SMALL TOWN.
Imperial Citadel
Tu Duc Tomb
Tomb of Khai Dinh
Tomb of Ming Mang
Thien Mu Pagoda
Walking street plenty of food near Truong Tien bridge
On the way to hue, can stop by famous Hai Van pass - It's nothing at all. Coaches will not stop, unless u hire yr own car.

I am not sure what's the attraction with Hai Van Pass. It's just an underground tunnel. And to hire a pte driver just to make that one-stop is it worth it? That's a question that only u can answer.

Btw to hire a local driver is no problem at all.... the problem is most of them can only speak Vietnamese. Ur right, with a driver u can specify where exactly u wanna go, but u still need to communicate with the driver to tell him where to drop/pick u up...esp around the Citadel as it's a no parking zone. So its back to the language issue. The last time I went with my group, we encountered this problem but fortunately I can speak Vietnamese so no issues.

Sorry my bad. I was referring to Hai Van tunnel which cuts through the mountains. Yes, ur right... the road leading up to the tunnel is quite scenic looking down at the coast etc. But it's very dangerous to stop along the highway if ur using a car. If u are really keen, I would suggest to rent a motorbike or go on a motorbike tour.

There are similar scenic drives along coastal highways all across VN eg the road leading to Nha Trang for eg.
