Buy ensorcelled mulhorand weapon set (bis weapon for leveling, if you cant afford the set, just buy the main hand, the offhand isnt that much important), and a healer companion (or a dps one if you're tank/heal), then you can focus on leveling, buy the +20% xp shirt/pants if you have some AD.
Run 2 clock tower a day for the rAD, as clandodge say, make a reroll lvl 11 to farm clock tower with both character, you'll make 25-30k AD a day just from that.
At level 70, if you're dps buy a blue 70 set power/crit/armorpen ilvl 135, it's really cheap and a good start, buy rank 5, 6 or 7 (what you can afford) dark enchantment in offense slot (you need 40% armor penetration for the soft cap in t1 dungeon (60% for bosses)), if you've already 40% armor pen, put power or azure instead, power is only better if you've a really low power rating (~1~2k). Put HP (radiant) in def slot to not get OS in T1 dungeon, you need at least 70k hp as a dps to start being comfortable.
With all this this you can reach 1600ilvl and go for t1 dungeon, I recommend you to farm lostmauth one time per day for the seal bag + daily free key = free chest
You need to start to buy an active companion and aim for 3*r12 bonding runestone, (it's a really important step for every dps char, as bonding runestone will basically break the game) Fire Archon are meta as active pet on PC (3 ring slot + power/crit/armor stats + ranged)
Besides this, you should do all the campaign daily quest everyday to unlock boons (GL with that

)
Well, it's a good start imo
Oh yeah, try to save 2.2m AD, buy 4.4k zen and buy a 6 month VIP with a 15% item discount you can find in invocation bags
