"Normal" (as as in, not Nex) GWD armour is sufficient for Slayer-related tasks. It's not a lot of money (for someone with your resources) it doesn't have to OSRS Gold be replaced and also gives offensive bonuses. It is recommended to keep an Barrows set in every kind of fighting style (Verac's, Ahrim's and Karil's) for the very few Slayer tasks that require a lot of defence.
Glacor boots are top boots for the moment. Barrow gloves don't look very good anymore, they're hybrid gloves so they may have some applications, but if I were you I'd go for the TWW automated gloves (Static Pneumatic, Tracking, and Static). They're the gloves equivalent of Glacor boots.
Amulet of Fury is an excellent amulet and the best hybrid amulet in fact. However, if you have funds to spend , you might want to purchase a Saradomin's Hers (second most powerful magic amulet after the Stream Neck), Murmur (currently the best melee amulet on the market) and Whisper (best ampoulet that can be used in a range).
Melee weapons are great if you don't have chaotics you could purchase Drygores. They're superior, however they are expensive. If you don't want to spend lots of money, you can use your Saradomin Godsword. (or get yourself a Dung and get maul)
Magic weapons are available for purchase Virtus Wand and Book, but they're even more expensive than Drygores. Seismic wand and Buy RS3 Gold singurarity are at a ridiculous price right now and the price on the website says that the wand costs 500 million dollars, but it's worth 2Bish. If you don't want to invest a lot, buy an Arma battlestaff. It's probably not as powerful as the Chaotic staff, but it's better than SoL at the very minimum.
