As for lower case fimenames and spaces, special characters...

I started back in 1996 with DOS format filenames after some hassles with various older systems (non-windows) on the net having hassles with my clever windows style filenames - I then tried to only use UPPERCASE 8.3 (DOS format) file names i.e. FOOLESHM.HTM for that reason. Windows carefully translates filenames like these into its own fooleshm.htm or Fooleshm.htm anyway...

Things may have improved nowadays with fewer people with older incompatible systems...

Metatags -- ahhh, that's a nest of worms - first consider why do you want to have the code generator name and all that sort of stuff taking up page real estate - it slows down the loading, and who is going to search for your page by all that anyway?

You might want your name... maybe date of last edit - but why not put that in the visible text content at the bottom of the page...

Two useful ones...

I had to substitute the square for the broken brackets to get this message past Cerebus... :- )

[meta name="description" http-equiv="description" Content="...."]

is useful for most search engines

and

[meta name="classification" http-equiv="classification" content="...."]

is worth consideration.

The content... well... pick words that will help people locate you - you also should consider some common misspellings for certain words too - although judging by some of the misspellings I have seen on the Mudcat - trying too hard that way lies madness... :-)

If you become known for something unique - use that word too - some search engines ignore things if you have too many words, or try to be clever and repeat words.

If you want to play the rankings game - ah, that's another matter... :-)
