Merge BAM to VCF. Which is the best workflow?

Dear All,
I am very new to the analysis of NGS data.

I would like to merge the information of sample 1029 from HGDP ( to SAN sample in Schuster et al 2010

If I well understood, I should call the variants from the bam file and then merge with the vcf. Is it correct? Could you gently suggest me the best way to do it in your opinion? When should i convert my files to the same reference sequence?

In addition I am looking at,
and I am trying to do Variant Detection on the example file NA12878. I have some doubt,
Where I can find MarkDuplicates tool? Should I invoke it just with -T argument? Or Do I need to install it?

I am really sorry, I am trying to understand GATK, but it is not rally intuitive, so of you have any tips or recommendation please let me know it.
