You could try swapping your OSRS GP platebody for torsion torsos, unless you decide you need the additional protection (which you likely don't) I believe that torag's platelegs provide the best defense as far the platelegs of barrow are concerned.
Otherwise, your setup is great for slaying. The only improvements you could do is to add a Skillcape and Soul Wars Cape, and an Chaotic Rapier. In addition, if planning to purchase Fury or Bandos I'd recommend you purchase the Fury first since it's the most affordable, and also has more bonuses than bandos tassets. Best of luck.
Personally, I do not like those who demand money.. When people are able to approach me and want to know how to summon/slay or something similar and I guide them to their appropriate locations and show them how They are very grateful which implies that they're actual noobs.
Then I gift them an amount of money.. Like in the region of 100k-500k.. It's not my intention to expect to see them become rich and pay me bk... Its just my way of giving thanks to the community. It's because when i just got mems, i had 2m money in my bank I went to this person in the fall for advice on how you could summon mythic creatures.. He explained how, became my current best friend on rs. He also I was given full rune + m money...
I've never asked for money in my life for rs, and ive recived over 10 million dollars in "gifts" from strangers who have assisted me more in their frndships, than cash.. Be aware, ive only been mem for about 5-6 months..
2 days ago, my most rich runescape gold 2007 frnd on Rs (22 the BIL banks) (also my dg partner) I borrowed 6mil to ensure I could purchase Ags (had 33mil, and the 6m he gave got me enough to buy Ags worth 38m and there was 1m left over for praypots) and told me to pay it bk at any time. Alrdy earned an additional 1m sincethen, and I should be able to pay him bk by the end week.
