It's not necessary to OSRS gold have a robin Hood hat or an archer's helm. one quick stat check the archer helm offers higher defence but the robin hat provides more ranged offense. The choice is yours as the differences are minor. Robins work great as a cosmetic item and can be changed to a different colour to earn loyalty points in Xuan in burthorpe or Varrock, but.
If you don't have them, you need to purchase some barrow's gloves. They are very effective to fit into the glove slot, and extremely helpful to use. You'll also need range boots If you want snakeskin, it is best to get them as ranger boots (12M) will not be within your budget.
A shield slot could include an illuminated God book. With Zamorak's novel costing 22 million an alternative is armadyl's Law book priced at 1.7M It's got 2 less ranged offence, however, it does have defence abilities and once you've illuminated it, you'll be rewarded with a huge prayer reward.
The cape you wear should be an ava's cape unless you're engaged in an activity that isn't going to work, for instance, shooting ogres in cages. If so, wear your most elegant ardougne cloak or a different one with offensive or prayer bonuses. Red dragonhide of course and unless you're looking to get out of the void. I hope that will help!
Looking at your charms I'm not entirely sure you're able to get the 69 you want without buying additional charms. With golds using barker toads there's a need for 1840 gold charms for 160k xp, greens for 1620, using Ibis, Crimsons it's 569 with stranger plants and blues you're probably going to need to keep, but buy rs3 gold it's 343 using kyatt's or graahks.
