A nice to have but not really a need to have, great for indoor smoking so you don't bosh your spent tobacco onto your brand new sofa but not entirely required as anything will do the trick.
Bags and Pouches
The following pipe briefcase was a birthday gift years ago. Purchased from an unknown source:
For many pipe smokers, a quality pipe specific lighter is an integral part of their pipe smoking experience. Others prefer wooden matches, citing that even the best lighters will taint the experience with fumes from the spent fuel. In matches, a wooden kitchen match works best, and to be sure a wooden match is not only affordable it is relatively safe for your pipe. Even matches can impart fumes, but those can me minimized or eliminated if one is careful to let the sulfur burn off completely before apply flame to tobacco. All experienced pipemen agree that using a torch lighter, such as intended for cigars, can quickly ruin a pipe. They are to be completely avoided by anyone who cares about their pipes. Choosing a good lighter, one designed for pipes and that matches your budget and sense of aesthetic, and then learning to use it carefully is a viable option for those that find matches are not for them.
Zippo makes an affordable pipe specific lighter in several styles. It has a special windscreen (pipe insert) with a hole that allows the flame to be drawn into the pipe bowl. Many pipemen swear by them and have learned to use them to minimize the impact of the fumes from the spent fuel. Others find that the naphtha lighter fuel imparts fumes regardless of how they're used. Proponents minimize the fumes by allowing them to burn off after first lighting the lighter and before drawing the flame into the tobacco, much like letting the sulpher burn off a match.
The three other major US non-butane lighter were the Nimrod Pipe Lighter, the Nimrod Commander, and the Beattie Jet Lighter.
Two Nimrod models were eventually manufactured. The Pipe Lighter model was unique in that it looked like a nut and bolt, and was lit by holding a thumb on the spark wheel, and pulling apart the lighter. A second model was the Commander (or Admiral), which resembled the current Zippo pipe lighter.
The IM Corona Old Boy is perhaps one of the most popular and successful butane pipe lighter. It comes in several attractive case designs. It is extremely dependable and aesthetically pleasing. It uses an older flint and wheel type ignition system. IM Corona makes several other pipe lighters as well. 
Dunhill makes excellent pipe lighters.
Colibri makes excellent pipe lighters, including the now discontinued "Clip" lighters made to clip in the shirt pocket like a pen.
An inexpensive but still refillable butane lighter is the IMCO. Not an elegant lighter, by any means, but a step up from a bic or generic cigarette type lighter and more importantly, one that is designed for use with pipes with an inclined flame.
Pipe Racks, rests, and stands
Pipe racks and stands come in many configurations, ranging from simple briar singles to more intricate ashtray models. Here are some for your consideration.
An easy way to clean estate pipes involving the use of boiling alcohol delivered via a glass tube attached to the stem with surgical tubing. It does not appear to be a particularly safe thing to do, so caution is warranted. The following YouTube video demonstrates the process: http://www.youtube.com/watch?v=SV-blwz7wKE&feature=related
Pipe tampers are essential. Used for tamping tobacco. Like anything pipe related they range from cheap and functional to works of art.

- German beer mug "Pfeifenclub Michelau" (Upper Franconia). In former centuries smoking in private houses was widely forbidden by fire police regulations. This was the origin of many a pipe or smoker's club. More recently many good housewife forbade her husband to smoke at home for the sake of the curtains. Humorously indicated on the mug by a bird escaping from it's cage.
