Hello Dalesman,
Rod choice depends on where you are going to fish, ie size of venue casting distance etc. Also you don't want a rod that will comfortably cast the lures you wish to use, too light a casting weight, and you could damage the rod on the cast, too heavy, and your casting distance will be impaired. Look for a rod with a casting weight from say 10 to 40 grams which will give you a wide enough scope for both Perch and pike as well as chub. A rod of about 8 foot should be long enough for most river lure fishing, I use an 8 ft rod for when I lure fish for chub/pike etc on the River Ribble, and it is adequate.Reel wise I wouldn't go too big unless you are using say a 400 size baitrunner reel, as you want to keep it all as light as possible. I use 35-50 lb braid with a short amnesia leader, or some Kryston flourocarbon then a 6 inch wire trace. This is of course just one of my lure fishing set ups, and I am sure someone else will give their thoughts on how they would go about this, so all info is good. Let me know how you get on.
Cheers
Chris.
