To quote the most plagerized information on the web! Just do a search for FW190 and you will come across several dozen sites which have simply cut and pasted the same info.
This is the standard armour package the ENTIRE F series was given:
"From the beginning, the most serious problem was large air plane weight increases. This came about not only as a result of the additional bombs load, but due to the need to introduce additional armor to protect the plane from ground fire. This armor consisted of plates protecting the fuel tanks, engine and undercarriage firings from below. Previously planned armor plates in the cockpit side walls were abandoned. This decision was made because the worsening overweight condition lead to a marked performance reduction."
And to quote the same information found on about 20 different websites dealing with the F8:
This deals with the canopy modifications:
"In the second half of 1944, a widened rear cockpit canopy was added with the F-8 plane. The purpose of this modification was to improve the pilot's side-forward visibility, important during fighterbomber missions. Armament consisted of two 13 mm MG 131 machine guns mounted in the fuselage and two 20 mm MG 151/20 E cannons in the wings. Most of the early production series F-8 planes had the additional armor used since the F-3 airframes. For weight reduction and improvement in flight characteristics it was not used in later F-8s. These planes had only the standard Fw 180 A-8 armor."

Now as to the Sturmjager Rustsatz's.....
Sturmjager, Sturmbrock, and Ramminjager all refer to 3 different A/C configurations. I knew the Ramminjager was a different varient however I always assummed the Sturmbrock and the Sturmjager were the R7/R8 Rustsatz's and were flown by select "Sturmgruppe" such as IV / JG3 which was the test unit.
According to The Luftwaffe profile series #4 FW-190 on pg 29 under the FW-190A8 varients chapter:
"The Fw-190A8/R7, initially designated "Sturmjager" (assault fighter) later recieved the designation A-8/R8. Fixed Armament for the A8/R8 consisted of two MG151's in the wing roots and two Mk 108's in the outer wings. The armour of the A-8/R2 was added to the windscreen and triangular side panels of the R7.
Many of the FW-190A8's flown in the assault fighter role featured welded, supplementary armour plates of 5 to 10 mm thickness on each side of the cockpit. These are called "Sturmbrocken". " Rougly translates to "battering rams".
I know that Maj Dahl's FW-190A8/R7 had additional armour around the entire engine compartment and extra armoured glass. Hope this clears up some of the confusion.
