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.

 Fluid Lighters
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.
 Butane Lighters
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. 
There are several good Old Boy copies to choose from as well. Among these are the Jifeng copy of the Corona Old Boy Pewter Finish with Pipe Shapes, the Yibao with Chrome Lines, and the Yibao Leather Wrapped. The Savinelli IM Corona Old Boys are made in Japan, while these copies are manufactured in China by the same company; Wenzou Yibao , who also manufacture other well known named brand lighters, such as Colibri.
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.
 Pipe Retort
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

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.
