I had a similar issue with having to learn some of physics HL by myself - it was just 3 chapters or so. I think the whole physics HL IB subject can be learned in 3,5 weeks if you do nothing else. I used a green A4 sized (probably by Kerr) book - don't know the name right now, anyway it came with a CD with all the contents of the book in pdf. I've made a copy of those PDFs - PM me.
I think any IB physics book that has chapters structured around the syllabus will be fine though. Also, download past papers - there's a torrent on most search engines. Past papers are an invaluable resource, just do them all.
