Occasionally if you approach the Hanged Man with Isabella in your party, she will say "Ahh The Hanged Man. Sometimes you wanna go where everybody knows your name", which is a reference the opening lyrics of the theme to the television show Cheers.

During a random conversation between Fenris and Varric, Fenris asks him "Who is Bianca?" When Varric tells him it is a crossbow, Fenris says that he must have named it after someone, to which Varric replies, "Nope, Mirabelle was taken", a reference to the rifle owned by Sir Roderick Von Fontlebottom The Magnificent Bastard from Jade Empire.
During random companion dialogue in the city between Anders and Isabella, she mentions that abominations are easy to escape because they make loud noises like "Grr Argh", which Anders refutes saying "Abominations to not go Grr Argh". During the ending credits of Buffy The Vampire Slayer, Joss Whedon's "Mutant Enemy Productions" credit screen shows a little monster which says "Grr Argh?"
During the second act, when you first enter your Hightown mansion Aveline will ask you to deal with a problem she has with the Templar Emmeric. During the conversation you will get a chance to question her about Emmeric's investigation. When you choose the question that asks her why she would not investigate it with the guard, she talks about the Gascard de Puis house raid, then finishes it by saying "Why can't he just build a boat like other old men." This is a reference to the television show NCIS and the main character Leeroy Jethro Gibbs, an old federal agent who builds boats in his basement.
It is best to plan your party from the start. While planning character roles, remember "One to take it, one to deal, one to weaken, one to heal". You should have a damager, tank, entropist and healer. This will ensure you have one member taking all the damage and bringing the attention away from the rest of the party. Have an entropist (probably Merrill) to weaken and demoralize the enemy, a healer to strengthen and maintain the party, and a damager to inflict the pain. This will ensure a well rounded party that covers all aspects of combat.

Take Isabella into the fade in the desire section. The demon will seduce her with the prospect of a boat in the harbor. When Isabella turns on you, she will say "I like big boats and I cannot lie", which is a reference to Sir Mixalot's "I Like Big Butts" song.
In the "Prime Suspect" mission when you meet Mr. Dupries, have Varric in your party. Give the sarcastic response of letting Dupries talk his way out the situation. Varric will make the comment "I bet 20 silver it's 'it wasn't me, it was the one-armed man'". This is a reference to The Mask when Jim Carey tries to defend his innocence when he gets captured.
In your home when your mother says that her children should be nobles now, your uncle says "And if wishes were poppy we'd all be dreaming right now".
