Then I found Tigra! It really does make things very very simple, and you end up with a great templated site, but one which you have so much control over.
As I said, I'm new to all this, and so following a chat with the vendor, they did the initial install on my JomSocial build to allow me to try it out. They made it so so simple, and I was incredibly impressed.
After 24 hours, I bought their template as it does pretty much all I need, and every question I've raised with them since has been answered rapidly, and exactly. Their support is truly excellent, and they're willing to tweak their templates to suit a users needs.
