Recommendations from me:
DFS in San Javier (english run, good friendly service, no pressure, reliable, decent prices)
IKEA in Murcia if you want to do it yourself. Recommend you check it out in the UK first because trying to negotiate the Spanish version is a bit tricky.
Electro Regalis in Roldan for electrical goods - spanish run and friendly, and v helpful. We've have white goods delivered the same day.
Dos Mares shopping centre in San Javier which has Eroski (like Tesco) and Woken (a big electrical superstore)
Electricity & Water - during signing we signed a form which gave Polaris authority to set up the electric and water accounts. You can then arange to get your electric bill online ( https://www.iberdrola.es/webibd/corporativa/iberdrola?IDPAG=ENWEBCLIHOGAR ). Unfortunately the water people don't have an online facility ( http://www.aquagest-regiondemurcia.es/index.php/aquagest/quienessomos )
Not sure what you meant by services?
If I can be of any further help, just ask. We bought on phase 2 last year and have been out 4 times and love it.
