Coopers DIY Beer Kit = Gales HSB

[hambrook]

First up a totally newbie wanting to learn. My favourite beer being Gales HSB even after it's move from it's ancestral home in Horndean, Hampshire. Also partial to a London Pride and Abbot Ale, so I have a taste for the sweeter, richer ales. And that's my Home Brew Goal, to create a sweet, smooth Ale, hey maybe even a Gales Winterbrew type brew one day.

First off; I'm trying to take advantage of the 25% off Home Brew offer at Tescos (until 22/12/14) so any tips as to what I should buy would be grateful received. So far I have:
- Coopers DIY Starter Beer Kit (Link: http://www.tesco.com/direct/diy-beer-st ... 3-7435.prd)
- Coopers English Bitter can (http://www.tesco.com/direct/coopers-eng ... 3-9947.prd)
- Youngs Beer Enhancer (http://www.tesco.com/direct/beer-kit-en ... 3-6255.prd)
- Youngs Beer Bottle Capper (http://www.tesco.com/direct/youngs-beer ... 3-5232.prd)
- Coopers Crown Seals (http://www.tesco.com/direct/coopers-cro ... 3-1626.prd)

Some questions:
1) Will the Youngs Beer Enhancer work / compliment the Cooper English Bitter kit?
2) If Gales HSB type beer is the end goal, what else should I add to the brew to enhance it?
3) Is there any advantage to saving bottling in glass bottles (Plenty of spares after xmas I am sure) vs the plastic screw tops
4) Do I use Coopers Beer Enhancer 1 or 2 ? I think it's Brew Enhancer 2 for ale?

Before the Tesco's 25% runs out anything else I should stock up on? Brew enhancer / Carbonation drops?

Many thanks for all help offered in advance
