Hi Evy
Thats great that you have lost so much, keep doing what you are doing in terms of cardio.
Weights wise you should be looking to increase your muscle mass ( the more muscle you have the higher your metabolism and the quicker you burn fat).
If your not used to using weights then you should be going for the 25 rep range to begin with, once you have built a foundation of muscle endurance then start doing 8-12 reps for exercises, this is the optimum range for muscle building.
The last reply is right in that to get the full benefits of toning up you have still a bit to go so losing weight (fat) whilst building muscle mass should be your goal. In terms of eating more protein, discount supplements are a good choice to buy from as they are value for money and offer decent products but to begin with just have a balanced diet. If you eat more protein than you need it just gets stored as fat any ways.
In terms of what you should be doing, what you should be using and how then a good website to use is
http://www.houseoffitness.co.uk/
They can produce programmes for you to follow together with instructional videos, all programmes are based on what your goals are, the equipment your using etc etc so it will save you lot of time and fuss. Theres also pages on product offers and also an info area which can give you some useful advice.
If not there are plenty of apps for mobiles these days which give good instructional advice, all be it in a general sense and you run the risk of it not suiting you individually.
Hope that helps
