SuStel:

The rest of the adverbials modify the sentence
by going before the object-verb-subject or law'/puS structure.

and if you had an adverbial and a noun with a type-5 suffix, which
would you place first ? I remember discussing this some time ago, and
no definite consensus existing on the matter.

I would put the adverbial before the syntactic noun, though there's no absolute rule about it. Okrand has mostly done it this way:

qIbDaq SuvwI''e' SoH Dun law' Hoch Dun puS
You would be the greatest warrior in the galaxy. (ST5)

batlh naDev SuDab
Welcome to this place (you inhabit here honorably) (PB)

QIt ghaHvaD yIn Hegh je vIghojmoH 'ej 'oy' SIQ ghaH
And teach him life and death, the slow and painful way! (PB)

vaj loghDaq lenglaHtaH Humanpu'
(thus humans can continue traveling in space) (SkyBox 99)

But he's also done it the other way:

tlhIngan Dujmey law'qu' SommeyDaq batlh cha'lu'
emblazoned upon the hulls of countless Klingon Starships (it has been displayed honorably on very many Klingon ships' hulls) (SkyBox SP1)
