Even as a new player starting during 0.4 I found the best approach to maps if find where you are comfortable and not dieing constantly (reminder a death is 10% xp loss in a map w/o an Omen of Amelioration or 2.5% w/). After that choose a single, to start with, type of map content (e.g. Expedition/Delirum/Abyss/Breach) to focus on and put 1-3 tablets of that type in along with your waystone. IMO if you are lack defenses such as non-cap resists or poor armor/evasion dont go juicing your maps to 6-mod 0 revive til you are comfortable its just gonna result in pain.
You can hop around the map to look for corrupted zones, cleanse those, then look for the maps with 'Has Immured Fury' and kill those for an assured Fractured Orb drop which sells for 20+ divines which will get you on your way to more gear. It doesnt matter what tier map you use. Additionally clearing either map that is surrounded by storms eve on the lowest tier possible (tier 6 for Jade Isles) can result in a gem drop that sells for 200+ divines.
Unless you have a true blasting setup its best to completely avoid the Vaal Temple til you have a better handle on the game.
