Hello fellow Wokinghamite (or whatever we are called?).
I'm quite new to the DSLR game and my equipment isn't as nice as yours but here's a few places I've shot in and around Wokingham.
In the Woosehill area where I live you can often see birds of prey and other interesting birds (if that's your thing). There's also nice woodland area just beyond Chestnut Avenue.
Not too far away is California Park where again is some nice wildlife and views over a lake. I took some great HDR shots there last summer.
Also in Winnersh is Dinton Pastures, which offers similar to California Park.
There's also another park nearby where I know The National Trust organise walking photography tours. Can't for the life of me remember the name though, I'll check with the missus.
Reading is probably the best bet for urban shots but there's also the Abbey Ruins and some nice opportunities when walking along the river.
I'm sure our wonderful county contains many more than that (Windsor Castle maybe?) but I've yet to explore it enough. I'll let you know if I think of anymore.
