Sometime/most of the time/all the time... what's most important is the data 
itself.

Try naked data, it's simple and healthy:

http://darkhorseanalytics.com/blog/data-looks-better-naked/
http://darkhorseanalytics.com/blog/clear-off-the-table/

If you would like something more, hmmm, interactive, leading to exploration and 
discovery, nothing quite beat a well constructed PivotTable:

http://en.wikipedia.org/wiki/Pivot_table

Quite a few very popular off-the-shelf softwares handle all of the above rather 
seamlessly.

Totally. 

JSON'ize your CSV appropriately and create, say, a cool Radial Reingold-Tilford 
Tree:

http://bl.ocks.org/mbostock/4063550

Don't forget to add some uber-cool animations:

Everybody likes animated Radial Reingold-Tilford Tree. Everybody.

And presto, you got yourself a winner.

There are two main aspects to SQL:  Data Definition Language (DDL [1]) and Data 
Manipulation Language (DML [2]).

DDL is was you design database with (create table, etc). DML is what you 
interact database with (select, update, etc).

In the same way as it's rather helpful to understand HTTP itself to build a web 
application, it's rather essential to understand database design if you build a 
database, irrespectively of sugar coating (ORM [3], MVC, and other TLA).

Learn about normalization [3].

Take a look at SQLite to get started [4][5].

Just in case 24GB is not good enough:

And, lets face it, 24GB is, like, nothing these days.

As always, it all depends on your requirements. For basic full text  
search, what comes bundled with most databases is Good Enough (SM).

Even SQLite comes packaged with a very handy full text search module:

You can see it in action bellow:

Personally, I would favor Markdown as it would address (a) and (b) out  
of the box, i.e. you can get fancy stuff in raw HTML if needed and  
people not aware of the syntax will get decent result out-of-the-box...

As an example, here is a, hmm, homemade wiki engine which uses Markdown:

http://svr225.stepx.com:3388/main

http://svr225.stepx.com:3388/main/editor
