Ah, a lab pet! They're not bad for 1-player, actually, as defence isn't
as useful in 1-player (in a war-type situation, as you keep beating an opponent over and over, he gets much stronger than you and pretty soon his strength boost is so much higher than your defence boost that he overloads any normal shields anyway).
Wand of Reality is a great weapon, and if you only do 1-player, any cheap 9 or 10-iconer (one of the aforementioned clubs or a scuzzys comb, for example) would be fine with it. I generally advise people to skip the 11-iconers (goo blaster, garoo elite blaster, and the other TCG blasters) because they're just not enough extra power for the price (1.2-1.5 million last I checked, maybe more now). Eventually, if you plan to do quite a bit of 1-player battling, you could pair a Bow of Destiny with that WoR.
Your hit points are too high for the GHS or blue ss to be any use at all, so your healing options are a bag of healing dust (runs about 8 mil) or a species healer -- gelert, elephante, and kacheek have the cheapest. Lennies have a good one, too, as well as a 100% species freezer. The faerie abilities restore/regeneration/healing vapour (pick one or two) will also help, healing 33% of lost hit points. What is your pet's species, and would you consider changing it?
Bombs are best when used on a frozen opponent, so pick up a freezer. A 100% freezer like H4000 helmet would run you about 5 mil nowadays, so snowglobe staff and black frost cannon are probably the best alternatives. With those, you may sometimes have to withdraw from a tough fight and heal if you don't get the first-round freeze... but when you do get a freeze, you can go all out with your WoR, Honey Potion and berserk attack and really damage an opponent.
Since your pet's defence is so low, you'll need percentage defence (doesn't depend on your defence stat) -- Downsize! is cheap and great; it blocks 50% of an attack (for one round). Winged Scarab is also a good weapon for people with low defence; it works in a really weird and hard-to-explain way, but the gist of it is that the lower your defence, the better it works. It blocks physical icons, which many 1-player opponents deal.
And like I said earlier, prickly potion is pretty awesome for a war-type situation once the opponent gets tough. It could be a decent backup weapon. And... I believe that covers seven of the eight weapon slots -- you can stick whatever you want in the last one. Purple sticky hand is great (stealing is disabled during neo plots, but a lot of Defenders of Neopia opponents have good things to steal), and a one-use bomb or a thick smoke bomb (one-use item that blocks all damage for one round) can come in handy during a tough battle.
Faerie abilities... burrow, sink and drain life are absolute musts. Regeneration/restore/healing vapour, as mentioned, are also great for pets with higher HP. Diamond dust (or fiery gaze) can sometimes freeze an opponent, so they're good, too.
Hope that helps.

But yeah, definitely sign up at IDB, because I think all battlers really benefit from getting a variety of advice -- sometimes the other raters/posters think of good ideas that didn't occur to me.
