Two gotchas when buying modular jacks. First, for ordinary residential wiring, you should buy the kind of modular jack with four contacts inside the jack; don't make the mistake of buying the wider modular jack with six contacts unless you're sure it's what you need you've got to look closely to see the difference.
Second, you can buy modular jacks either with or without the wiring block this is the heavy plastic piece which you mount to the wall, with screws to attach the wires to; see the picture higher up on the page. If you're installing a totally new jack, then you need the wiring block. If you're upgrading an existing, old-fashioned pre-modular connection to a modular jack, you might be able to use the existing wiring block, in which case you don't need to buy the kind of jack with the wiring block included; sometimes you can take the old cover off and just put a new modular cover over the old wiring block.
In the store, it's hard to tell from outside the sealed package whether the block is included. Read the label carefully! More than once I've gotten home and realized I bought the wrong kind; it's an easy mistake to make. As mentioned above, you should buy Cat 5 wire for all new phone wiring projects. The older four-color type allows more crosstalk between wires; this might be only a minor annoyance for voice lines, but it's a bigger problem for modems or DSL lines.
Even if you don't have immediate plans to transmit this kind of data across your line, it's better to plan for flexibility in the future. Cat 5 is now the national standard. You can also check at the Network Interface Device to make sure the phone company doesn't have the polarity reversed; if they do, you should call them to have it fixed at no charge, since reversed polarity can reportedly damage some kinds of phone equipment.

Using rags and water, carefully clean the outside of any obvious dust, making sure not to get water into the electronics removing the parts to clean first can make this much easier.
Then use steel wool to gently get rid of any other imperfections that may have accumulated over the years. Be gentle with this as sanding too vigorously can lead to going through the paint! With care, we were able to completely remove some unwanted spray paint that had accidentally found its way onto this phone. Even in spots where the metal underneath is exposed, using the steel wool can help to "blend" the margins so they're not as harsh. Once you've cleaned it, it's time to get into the electronics!
