Another truth universally acknowledged is that this opening line is one of the most famous, and most often parodied, in English literature. See here for an entertaining list of variations, including the opening of Bridget Jones's Diary.

A chaise, from the French for chair, is a small light carriage. Some have two wheels, pulled by one or two horses; others have four wheels with as many horses.
This particular quote implies a chaise and four horses. It is mentioned by Mrs Bennet as it shows how wealthy Mr Bingley is.

A man could not introduce himself to someone of higher standing than himself, nor could he introduce a friend to his acquaintances without their consent. Women always had to wait for men to initiate the introduction, and they could not be introduced to a stranger without an acquaintance conducting the meeting.

HertfordshireHertfordshire is a county in the southeast of England. Home to the Bennets, it is the setting for most of Pride and Prejudice.
Regency young lady playing the pianoforteGirls belonging to the upper classes spent most of their time learning skills or accomplishments that would theoretically help them attract a husband, and which were therefore often neglected after the wedding.
An accomplished girl might have learnt to draw, sing, play music and speak foreign languages.
The numbers Mrs Bennet mentions refer to sets of English country dances. The Boulanger was an easy dance, derived from the Cotillion, which allowed every lady to dance briefly with every gentleman.

The fictional town of Meryton in Hertfordshire was probably inspired by Hertford.
Lacock in Wiltshire was the 1995 BBC television series choice for this location, while Stamford in Lincolnshire was chosen for the 2005 movie.

The building, which still stands, ceased to be used as a royal residence not long after the death of Jane Austen.
A hack chaise is a carriage for hire, like a taxi, used by those without the means to keep their own carriage. It is presumed that Mr Darcy would not want to talk to Mrs Long if he knew she used that mode of transportation.

Vingt-un or Vingt-et-un is the French version of what became Blackjack, with a few alterations. Vingt-et-un, French for twenty-one, originated at the beginning of the 18th century in French casinos.
Commerce, on the other hand, was invented a century later, also in France. It is similar to Vingt-un, so the comment regarding which Jane and Mister Bingley both like best shows how little they know one another yet. This is, of course, the point of the comment made by Elizabeth.
