IETF 121 Map of Dublin
Generally Dublin city is relatively safe, but it's a city so nornal rules apply. In terms of the location, mostly you'll find better things south of the river from the convention centre. The area around Grafton Street (+/- 0.5km or so) has plenty of bars and restaurants and is generally the direction to head in the evenings. The grand canal basin, almost directly over the river from the convention centre has some shops/bars/restaurants and is a reasonable place to head if the weather's ok. The couple of blocks north of the convention centre also have some shops and a few restaurants.
If you want to join many other tourists then goto temple bar. It's not terrible but there are better places.

More information on getting around Dublin
For bus, train and trams, you can use the LEAP card. You cannot use your debit/credit card to pay on busses, trains or trams. A basic bus trip (which is most all of 'em) is €2. You tap your card on entering the bus from the front door. For trams and trains you "tap on and tap off" on the platform. You can add credit to leap cards in many newsagents or using machines at train stations or tram stops or from your phone if you install their app and have NFC etc. I don't believe the leap card can be used on the airport coaches, though there are (slower) Dublin Bus services between the airport and the city where leap cards do work if you prefer that.
¶ Tipping Culture
It's normal to tip in some situations in Ireland, but not obligatory.
Tipping ~10% for table service in restaurants and cafes is customary if they didn't already include a service charge. The bill will say if a service charge is included - usually it isn't for fewer than 6 people. Tipping in bars (if you don't eat) and for over-the-counter food purchase is optional and not that common for locals. Tip jars are common, but discretionary.
A taxi driver will never decline a tip.

The National Museum of Ireland's Archeology collection has a huge collection of Prehistoric, Viking era, and Early Medieval Religious objets d'art including several very fine gold hoardes.
The Book of Kells from the fourth century is one of the finest illustrated manuscripts on display, in a library which many will know from films for it's evocative internal architecture. Entry is not free (George Lucas denied ripping off the look and didn't seek permission to emulate it, according to the web)
