(After Vukovar, Tomislav Mercep was involved in ordering the torture and murder of imprisoned Serbs in Gospic, according to the confession of Miro Bajramovic)
Serb reports here show the YPA didn't really do anything to help them and was passive while all this was going on, but in certain villages Serbs were able to save themselves from cleansing by putting up barricades. It appears only after Croats directly attacked the army or its members or with great show of force, barricaded them - or tried to -would actual fighting between Croat armed forces and the YPA start:

At the beginning of Croatian-Serbian confrontation in Vukovar municipality, YPA troops in the Vukovar garrison, acting upon the order of army leadership and Presidency of SW Yugoslavia, did not interfere in the conflict, but tried to act as a kind of impartial peace force. However, they were inconsistent in these efforts - for instance, they interfered on 2 May 1991 in Borovo Selo to save Croatian policemen, but stayed in the barracks when Croatian armed forces spearheaded forcible "cleansing" actions in Borovo Naselje (4 July) and Luzac (25 July) against the Serb population. Their members, with the exception of reserve troops from Vukovar, moved freely about the town even when Vukovar Serbs could practically no longer get out of their houses. The first major incident between YPA and armed members of the Croatian Democratic Union party militia occurred on 20 August 1991, when privates Dejan LAZAREVIC and Ljubo BRADULJEVIC were attacked in the Vukovar post office, where they used to come every day to pick up mail and money orders for soldiers in the barracks
The new incident, which led to the first WA intervention against Croatian armed forces in Vukovar, happened on 25 August 1991, when Croatian soldiers, near their barricade on the way out of Borovo Naselje, planted an anti-tank mine under a YPA truck, the passage of which from Vukovar to Borovo Selo had been duly announced to the Croatian police
Judging by this report, Vukovar was then for a few hours under full control of YPA units, which also took possession of the road towards Bogdanovci, the only way which the Croatian armed forces could use to enter and leave the city. However, at the request of the Croatian party, cessation of hostilities and return of YPA units to the barracks was arranged. This was a trap from which they could not get loose until 18 November 1991.

However, this doesn't excuse the brutality unleashed upon the Croatians by the Serbs in any way.
The Serbs screwed up in Vukovar, after that the diplomatic tide had turned. Individuals like James Baker III and Lawrence Eagleburger turned on their former protege Milosevic after assuring him of tacit support in keeping Communist Yugoslavia together in June of 1991.
The use of the Serb paramilitaries was Milosevic's way of creating "plausible deniability" which has insulated him from direct responsiblity to this day, no matter how Vojislav Seselj insists that Milosevic directed the entire operation.
However this use was a double-edged sword as the paramilitaries were criminals and their behaviour was atrocious.
The Croat-Serb gripes are at an end, as conservatives on both sides see that the larger enemy is foreign sponsorship of Islamic elements in Bosnia.
Liberals on both sides continue to work as puppets of the international community, exemplified by individuals such as Djindjic and Mesic.
There is no stomach for a fight with Croatia in Serbia, as the objective is and will remain Kosovo.
Be seeing you,
