In general, are there any major drawbacks when applying to PhD programs to start in the spring? Is chance of admission much less likely?
After my undergrad, I won a scholarship to do research in Germany for a year, and after my year I want to start a PhD program in Physics back in the US. The academic year in Germany goes from October to September, so I can't apply for admission for Fall 2011, unless I cut my studies in Germany short. Additionally, I only just arrived a few weeks ago, and I barely know my professors and research advisor here. I feel like I could get far better letters of recommendation from my research advisors here if I waited a year to apply.
Would it be recommendable to wait and try to apply for admission for Spring 2012 to programs, instead of applying now for Fall 2011?
The deadlines would be right around the time that I'd be done here next year, then I'd probably have a few months off before I start a program in Janurary 2012 (if I got accepted!).

Also: Does having this extra year of research after my undergrad make my application look better than someone who is fresh out of undergrad?
