Newbie wondering if i would be doing the right thing.

Yep get the Vg from Boots, also look on ebay for PG, there is Pharma grade for £6.95 inc p&p for 1 litre.
It is best to buy a starter kit first, and Terry at leisure liquids is brilliant!
Also if you check Fleabag's posts she has found a good range of concentrates.
