Install database , application and search index on Single machine ?

Under SAP PROD PAK SERVER 4.3 -> Windows Server on IA32 32bit (SAP Education Products" SAP PRODUCTIVITY PAK BY ANCILE" SAP PRODUCTIVITY PAK 4.3) I am only getting the below files-

RWDuPerfServer43P_1-10009622.ZIP

RWDuPerfServer43P_2-10009622.ZIP

Is this the right server software ?

- Can we install database , application and search index on same machine ?

- OS is windows (2003, 2008, ???), Is RWD only supported on 32 bit windows with IA processor or any processor and also on 64 bit ?

- Where can I find the installation document or all the prerequistes ?

- Which database is preferable SQL, oracle or DB2 , currently we have SAP system on DB2

- Do we need to integrate the RWD with all SAP system landscapes ?

- Also suggest the hardware requirement (RAMprocessorhard disk space) if 1 server installation is possible for all the req (Search Server + Database Server + Web Application Server + Administrator Workbench)

Thanks
