Dear SPSS-L experts

I haven't done meta-analysis before but I need to do it now. I am trying to teach myself about meta-analysis and would like to have some wisdom from the experts here.

My problems is that I have results from 16 studies and want to do meta-analysis for two regression coefficients  

My data look like this:

study	b1	b2	sample size		coefficients standardized?
S	-0.06	0.14	549		unstandarized
P, T, & H1	0.34	0.04	101		standardized
P, T, & H2	0.15	-0.1	129		unstandarized
P, T, & H2	-0.19	0.25	241		standardized
S & D	0.39	0.07	132		standardized
T, R, & C	0.39	0.07	132		standardized
G	0.66	0.31	632		standardized
G & H	0.02	0.24	506		standardized
L & W	0.1	0.13	1335		standardized
L & T	0.25	0.41	232		standardized
M et al.	-0.18	0.18	198		standardized
E et al.	0.25	-0.01	359		unstandarized
S et al 1	0.26	0.18	167		unstandarized
S et al 2	0.01	0.37	167		unstandarized
N & F 1	0.26	0.12	152		standardized
N et al	0.09	0.33	520		standardized

Some coefficients were calculated mathematically and I don't have SDs for those coefficients.

Can I find numbers for overall effects for two variables through meta-analysis? 

What are the methods and programs that I can use for this kind of analysis.

Any help will be greatly appreciated!

Thanks in advance,

Sungeun
