The bike is fitted with a 190mm eye-eye shock.

Not really, it will compromise the suspension geometry too much.

The bike is designed to run a 190mm length shock with 50mm of shock travel.

The Rear Shock unit on this bike does not come with lockout.

Some 2.5" tyres may be too wide, you will have to choose carefully to allow enough mud clearance.

It depends very much on the conditions (wet mud etc) and the tyres, 30-35psi is about average.

An indicative weight of the Carrera Banshee is 15.4kg, heavier than standard MTB's due to its full-suspension.

The Banshee's rims will accept a 2.3 tyre fine. However, tyre sizes vary dramatically between manufacturers and as a result it is always recommend that you check the frames tyre clearance before riding the bike.

The Banshee will accept a Downtube Mudguard. These generally fit using high tensile rubber bands that wrap around the frame and hold the mudguard in position. The Crud Catcher (134794) is an example of this style of mudguard. Alternatively, you can use a Fork fitting mudguard such as the Topeak Defender FX (593822), this fits under the steerer tube of the fork and is also compatable with this bike.

In principal this will work fine. However, everytime that the cassette is changed the gears will need to be retuned, especially the 'B Knuckle' which determines how much slack is in the chain. To change the cassette you will need two specialist tools; A Cassette Lock ring remover (item code: 969741) and a Chain Whip (item code: 955518) as well as an adjustable spanner.
