Lund is at its fastest 10 minutes by train from Malmö and an 47 mins to/from Copenhagen, including its airport. All trains  (pågatåg, öresundståg) stop at Lund, including the X-2000 expresses from Gothenburg and Stockholm. There are also buses from Malmö.
Lund is certainly small enough to see most of it in an afternoon's walk. You can pick up a city map at the tourist office at Stortorget square (adjacent to the Town Hall).
The local Skånetrafiken buses  can get you to most areas of town. The hubs are around the train station, Botulfsplatsen, and the University Hospital (Universitetssjukhuset). Tickets are 21 SEK for as far as you want to go, if you're under 19 it's 13 SEK. Slightly lower prices available if a prepaid card is used, 17/11. If you are traveling as a pair, ask for a Duo ticket to save a few SEK. Note that, as in the rest of Skåne, the buses do not take cash, so you have to buy your ticket in advance! This can be done by using the ticket machines at the train station, Lund C. You can also buy prepaid (200 SEK) cards for Skåne buses and trains in Pressbyrån stores, there are three by the station and one by Botulfsplatsen. The yellow, regional buses accept payment through credit card.
The best places to catch a cab is by the train station or by Botulfplatsen. Unfortunately you can not rent bikes anymore at the station (state: June, 2012).
Lund Cathedral (Domkyrkan) was built in 1103 and is the second-largest cathedral of the Nordic countries. There's a free organ concert every Saturday morning at 10:00, and the elaborate astronomical clock (on your left after entering) puts on its show twice a day (12:00 and 15:00). This clock show is highly recommended even if you're not interested in the church, due to its nostalgic value.

Lund is an extremely safe town by international standards and there is no need to avoid certain areas. Even late-night walks through the darkest and most desolate back streets are relatively safe and most local residents walk home at night without any second thought.
On weekend nights, you may encounter rowdy groups of drunk people (mostly students). However, they are seldom violent to third persons, and are often notably polite by international standards.
Other than rampant bicycle theft, crime is virtually non-existent.
The only violence you are likely to encounter is from night club/student nation bouncers, which are notoriously rough.
