Hi Teddy
the gear you have been offered isn't terrible, but if you are just starting out I'd personally steer clear of "quick drag" reels.
They take a bit of getting used to, and in the early stages I personally think you would be better served with a couple of "baitrunner" reels. Much easier to get on with.
Also, I'd try to get two matching rods if possible. The two you mention are going to have completely different fish playing and casting characteristics to each other.
I'd stick with 2.75lbs, these are going to be able to cast reasonably well, and will land any fish you are likely to encounter in any water you visit. A good starter rod is a Daiwa Black Widow G50. These can be picked up for around £35.00 a piece if you shop around, and I personally think you would get more pleasure out of fishing with these than the two you mention. https://www.total-fishing-tackle.com/daiwa-black-widow-g50-carp-rod
With regards reels, the two main brands are Shimano, and Daiwa. Between them I reckon they have about 70% of the market sewn up, and it really is personal choice which ones you prefer. Another make worth looking at as they are normally well screwed together and perform well are Okuma. A bit cheaper than either Daiwa or Shimano, but will last you donkeys years if looked after. I have used all three makes, I personally prefer Daiwa, but as I say, it's all down to choice and I certainly wouldn't knock either of the other two makes.
Daiwa offer a Black Widow reel to match up with their Black Widow rods, and again they are the perfect choice for a starter set. Reasonably priced, they would be a better bet than the Crosscast 5500 quick drags as they are a baitrunner (or bite 'n run as Daiwa call it).
Two of these in 4500 sized at £38.99 each and you'd be away.

So there you have it. Just my opinion, and for a total price of 157.96 you are going to have two matching rods and reels that you could happily fish anywhere with. And when you do upgrade (because you will believe me) you'd get more money for these selling on than the mismatch you've been offered.
