SQL Server Infrastructure Evaluation

Question

I am trying to come up with a check list / guidelines for evaluating Existing SQL Server Infrastructure.
Evaluate Existing Capacity , Data growth Rate , Capacity Predictions, Security Model , Availability / Disaster Recovery Options, Configuration Options, Table / Index Design Guide lines , Performance Tuning Guide lines, Hardware Selection , RAID Providers,
etc.
I want this be useful information our team can reference for making decisions.I am planning to spend about 100 hrs gathering and documenting this information. 
Has anyone done similar kind of guidelines for his / her team. I would love to learn what approach to follow?
I would appreciate pointers and useful links on this topic.
I know its really big ask. I am taking this task because I work for extremely small organization with limited resources and limited knowledge. I want to provide meaningful documentation for my team which doesn't have much expertise. 
Thanks,

Answer 1

What you are asking for is a mix of -
Guidelines/Best Practices - for infrastructure setup and capacity planning, development, maintenance
Trend Analysis - for maintenance and capacity projections
System Documentation - for maintenance and identify opportunities of scaling up/out
Guidelines and best practices will have to be looked upon from different sources e.g. MSDN, blogs, SQLCAT whitepapers, forums, technet wiki, books etc.
You will have to create and setup your own processes that gather trends like disk space, database/table sizes, CPU, frequently used and/or heavy queries etc. Some of this information can be had from DMVs or you can write own stored procs, SSIS
packages or maybe even consider using some 3rd-party vendor tools.
Same goes for system documentation. It has to be created and updated manually using the options described above for trends.
The system documentation can be gathered quickly but the others will take time and patience! Good luck :-)
