Certainly recommend a day trip to Wicklow! One hour and your in beautiful wild landscapes. Places of particular interest are Glendalough, Luggala, Powerscourt, Avoca, Sally gap, Glenmalure, Lugnaquilla etc. Wicklow is beautiful and has mountains, forests, lakes, rivers, waterfalls, ancient sites, colonial estates and plantations etc. If you want to hook up with similar minded people then maybe you should join Couchsurfing: http://www.couchsurfing.org/.
They have a "Hiking In Ireland" group on this. People always looking for hiking team ups!
Many B&Bs in Dun Laoghaire:

This is a great base for Dublin and Wicklow (google earth it). It's on the seaside, has 2 pier walks, promenade, nice view over Dublin Bay. Biggest marina in Ireland, decent cafés and a nice Sunday market. And the DART electric train only takes 20 minutes to city centre. It is very well set up! If you are in that area at some stage then check out the famous "Vico Road" area between Dalkey and Killiney. Scenic and glamorous!
Re Dublin City attractions, well what are you looking for?
