RAM normally gets 'used up' by caching information.  Normal Unix 
behavior.

Why use 'less' to dump output to a file?  I s'pose it works, but 
normally just plain 'cat' is used... :)

Not a problem at all.

That's unusual...

What does a 'free' command show? Here's mine from a 512 MB RaQ4:

[root root]# free
             total     used     free   shared  buffers   cached
Mem:        517104   487392    29712    47376   156524   248300
- -/+ buffers/cache:    82568   434536
Swap:       131448        0   131448

So I only have 29MB 'free' but all that space in 'buffers' and 
'cached' (405MB) will be dumped and reused as needed by the system 
automagically.
