This can be achieved in many ways.
To generate publication quality alignment graphs of sequences, the best way is to download the actual sequences for each species, and use some programs such as VectorNTI to make the alignment.
To retrieve promoter sequences, you can use UCSC genome browser. Promoter sequence for a gene can be defined as the sequence upstream of the TSS of the gene (as shown in the screenshot below). So once you have identified the gene in UCSC, you can ask the browser to give you the DNA sequence upstream of the gene.
