So I had some BTC on an older Windows computer with an old version of the BTC client, 0.3.x.    It was crashing on me after a minute or so of being open, and I kept restarting it and finally sent all my BTC to an address of a wallet I had stored on another computer

I closed the bitcoin client that was buggy/crashing on me right after sending the coins.   I backed up the wallet.dat and moved it to a computer with a working (latest) version of the bitcoin client.  It was fully synced up with the blockchain before overwriting the wallet.dat.  When I launched the client it showed my transaction in the tx list but it was 0/confirmed, and still is (this is about a week after sending the coins).  The balance is 0 so the coins are out there 'in limbo' and blockchain.info doensn't have any record of the transaction and they never arrived at the destination

what do?

I was running bitcoind 0.3.x and 0.4.x on a freebsd virtual server and it ran pretty well.  It was compiled from source from the freebsd ports tree.   I now am trying to use bitcoind 64bit binary downloaded from bitcoin.org on a CentOS 6 virtual server, and it seems to use a lot more memory and cpu than the older version I was using.  Also, "bitcoind getinfo"  will lag over 30 seconds sometimes before responding. When it finally responds, subsequent getinfo calls return quickly, but if you wait a while it hangs again.

Also my app which communicates to bitcoind via rpc to make new payment addresses and such will also have very slow response at times, and if the delay goes over 30 seconds my load balancer gives up and it screws up the transaction (unfortunately I can't increase the timeout on the load balancer)

should I try getting the latest bitcoind compiled from source to see if the performance is better than the provided binary?  Is there some other trick I'm missing regarding why this is happening?

Lets say I have 90 bitcoins, and I make a backup of my wallet.dat

then I manually make 10 new receive addresses in my wallet by going to address book->receiving-> new address and receive 1 bitcoin each to each of those addresses, now I have 100 bitcoins.

Now lets say I lose my wallet.dat due to hard drive crash.  If I restore my backed-up wallet, will I have 90 or 100 bitcoins? 

I know they can grab .com's, I assume .net and .org just the same.   Bodog casino had their .com snagged, they moved to .eu so I assume these are safe.  However, I am guessing you don't want to buy it from a US based domain registrar as they could be forced into revealing who owns it and into taking it down.  Can anyone recommend a registrar that I'll be reasonably safe from the US government?  And for that matter, a hosting company with inexpensive VPS servers that won't cooperate with the feds?
