Advice for study prior to Therapeutic Radiography

I am currently in the army and hoping to serve another 4 years before applying to Queen Margeret University to study Therapeutic Radiography. However I dont know if I have any chance of getting in. I got good grades for my standard grades and stayed at school for my highers but then got bored of school and didnt really bother with the exams so I only have the units which leaves me with very little UCAS points. I have a few NVQ Level 2's in irrelevant subjects (search and munition disposal being one) so am looking for advice on what is best to do over the next 4 years to help me with the application. I am looking to apply for an open university course in Health Sciences. I'm considering the 2 year higher certificate as this will give me 120 credits but I welcome any advice as to which level to study. I believe this will help along with hopefully finding some voluntary work nearer the time and generally reading into the course and the career to have as much knowledge as I can. Does anyone have any advice? Also i'm so excited about all this as i'm now 26 and this is the first time i've really found a career I want to do so want to start studying something as soon as I can! Can anyone recommend any textbooks either for Health Sciences of Radiography that I can start to read?
