Poly-bushes and leave the ARB's for sure. ARB's are a compromise between grip and feel but firmer bushes will be nothing but good for performance.
If the car has a tendency to oversteer/understeer then changing one or the other ARB can be a great way of balancing the handling, (stiffen the end you want to make looser, so bigger rear ARB to reduce understeer and vice versa.) but stiffening both ends of the car has much less benefit. It'll make the car feel more 'nimble' but may actually reduce the grip levels available. You'll find the bushes make the car feel more nimble too, but they'll also make it more predictable on the limit and usually improve grip.

Polybush for the win as makes the car feel so much tighter anyway
Would think you would notice the effects of polybush more than doing the arb

Really I was under the impression arbs made a huge difference

They do mate but you'll notice more of a difference I would say doing all the std bushes in poly bush , pretty useless IMHO just doing arb when all the other bushes are soft and gooey and moving about

Don't get me wrong, ARB's can be a good upgrade (depending on the car) but replacing old bushes with firmer ones is a much better first step. ARB's are more of a fine tuning thing, while bushes are an essential part of the suspension. When they're tired they'll negatively effect basically everything about the handling.
Do you know what the current and uprated ARB sizes are? It all depends on balance and what you're after. Stiff ARBs will make the car turn in and change direction quicker, but their effect on grip's not always good.

i think idealy aim for both
i guess poly bushes will be most noticable if yours are worn and tired , ive fitted uprated arbs and they make a nice differant , better handling without any more harshness or nastys
