A 'rack' is just a term for a collection of climbing equipment that makes climbing possible with some degree of safety. The items that make up a rack, and quantities needed, are very much determined by the style of climbs being attempted. Long, well-protected face climbs may need several sets of wires, lots of quickdraws and a few cams, whereas short gritstone routes can be protected by a few cams and a handful of wires. The aim is to have enough gear to never have to climb past a useful placement, but not so much that the weight of it is excessive.
A rack of gear
To give an idea of how racks vary, here are some examples:
Harness - £35 to £60
TOTAL - £141 to £264
Leading short pitches (20m or less)
All the above, plus:
TOTAL - £276 (£417) to £475 (£739)
Leading long pitches (20 - 60m)
All the above, plus:
TOTAL - £155 (£572) to £300 (£1039)
For high grade routes (E1 and above)
As above, but add:
TOTAL - £120 (£692) to £210 (£1249)
Cost - As with everything in life, you get what you pay for. Cheap gear will not last as long and may not perform exactly as you want it to when in a position of extremis although all gear should have passed the relevant safety performance tests (be wary of ultra-cheap cams bought from Eastern European web sites though).
Second-hand gear - You should always be wary of buying second hand versions of anything you have to trust your life to. With climbing gear it is often essential to know the history of items like ropes - has it been used to tow a car, or stored in direct sunlight for 6 months? With other items it is less critical since most of the metal items like krabs and wires will show their wear. In general steer clear of buying second-hand soft gear like slings, ropes and harnesses.
Ropes - It is usual in trad climbing to use a pair of half ropes, and for each partner to supply one rope, though for routes under 25m, a single 50m half rope can simply be doubled-up. The price of a rope hasn't been included in the calculation below but you can expect to pay around £50 to £100 for a 60m half rope.
