I'd recommend a power rack and building around that. The cheap £130 one I bought form ebay has been alright, my only complaint is that the nuts and bolts are cheese grade specials, and after disassembling the rack to move to a new flat, half of the bolts ended up with no discernible thread. Ended up ordering new M10 nuts and bolts, A2 stainless no less, all's good again.
The power rack's horizontal bars have saved me from dropping a few kg on my face on more than one occasion, I'd never bench press solo without them. Point being, what ever rack you go for, get one with face and self-asphyxiation protectors - or what ever they're called.
As for the bar, the minimum that'd fit on the power rack is a 6ft, but barely so a 7ft is recommended. I currently use a 6ft bar from Mirafit (link below), it's as cheap as the horrible stuff you find on ebay but it's actually really nice for the price. Plates, the cheap DKN and Body Power Olympic plates from ebay are good value, aesthetically they're a bit rough... but whatevs'.
I can't recommend a bench because I fabricobbled mine out of 3x2's.
Also, rings are nice to have to do dips and stuff.
Here's my set up:
