Err...in my history books, the Napoleonic wars ended in 1815 after Napoleon was defeated at Waterloo - that was 3 years after the war of 1812. No "crack English troops" were deployed from the European theatre to America, indeed the Canadian garrison was milked of the best soldiers because they were needed in Europe.
Let's straighten out some timelines.
May, 1808 – April, 1814 Peninsular War (Napoleonic War)
June, 1812 - War of 1812 starts
April, 1814 - Napoleon abdicates
April, 1814 to January, 1815 - England reassigns Napoleonic War troops, some to America to support the War of 1812
December, 1814 - Treaty of Ghent signed, ending the War of 1812
January, 1815 – Battle of New Orleans is fought
March, 1815 – Napoleon escapes Elba
June, 1815 – Battle of Waterloo is fought
For nine months prior to the battle of New Orleans and three months afterward, Britain was not at war with anyone except the U.S.

I am sure there are others, but I could not find records.
Again the RN was rather preoccuppied with the French fleet. It never sent its best to the Americas - why would you if you had one of the world's largest armies (ie the French) on your doorstep rampaging through Europe?
Of course by the battle of New Orleans this had not been true for nine months.
Again, have to disagree. The whole purpose behind the war of 1812 was an attempt to get Canada to rise up against the "English oppressor". Britain had no interest in fighting America in 1812 - it had its hands full on Continental Europe. Note that the peace treaty between America and Britain was signed before the American victory at New Orleans. America didn't force Britain to the negotiating table, rather Britain didn't want to fight America whilst also taking on Napoleon.

causes of the war of 1812
The War of 1812 was thus the first war "sold" to the American public via popular appeal. On June 1, 1812 he gave a speech to the U.S. Congress, giving several reasons for war:
Causes of the war of 1812.Ongoing impressment of American sailors into service on British Navy ships, an insulting breach of American sovereignty; Britain's navy "violating the rights and the peace of our coasts";
Britain's blockade of U.S. ports ("our commerce has been plundered in every sea");
Britain's refusal to repeal its Order-In-Council forbidding neutral countries to trade with European countries, and the British Navy's enforcement of this order;
Britain's incitement of Native Americans (conventionally referred to as "savages") to violence against the Americans.
There is evidence that the western areas of the US wanted Canada and believed it would be a easy conquest and the Southern areas wanted Spanish Florida. Many Northern states were not for the war. To say that the whole reason for the war was to incite Canadians to rise up against their oppressors is simplistic. What riled up the population was the violations at sea and impact to commercial operations, not a desire to annex Canada.
