No, you also have to make sure that

  • your USB (or at least your wallet file) is encrypted with a strong password (otherwise, what happens if you lose your USB or it gets stolen?)

  • you have at least one, preferably multiple remote backups somewhere (otherwise, what happens if your house burns down?) and any backup must be encrypted as well (otherwise, what happens if the remote backup location gets hacked / confiscated by the feds / stolen by a fraudulent employee / etc?)

  • you only insert the USB stick in a computer that is guaranteerd free from malware/virus/spyware/keyloggers/trojans/etc (or at least whenever you actually enter your password to unlock the wallet and confirm any payments)

In theory, there's no difference between theory and practice. In practice, there is.

What it sounds like is can make this wallet file; save it on an SD card. Lock it up in my closet.  Then deposit coins to the address associated with the wallet.dat file with out having to take it out of its 'spot' UNLESS i want to pull coins out of my savings?  If so this is awesome! I'm looking forward to setting this up.  Thanks for the post!

Correct. Although keep in mind what I wrote above about encrypting the wallet file (even if it's stored on a USB drive or SD card) and remote backups.

i think just keeping Anti-Virus up to date, will save my bitcoins from 12 years old lame hackers. There is no need to be paranoid about wallet, if here isn't really BIG amount of BTC

...
2. Wallets stolen from RAM:
You CAN'T do this even if the computer is running nothing BUT bitcoin and malware:

Every program has a ram space, other programs can't touch it.

This means that even assuming data stayed alive in RAM a while (I never heard of such):

The virus would need to allocate almost ALL the computers RAM to itself in order to even get access the residue after the bitcoin client closed THEN it would have to search it.

This would slow the PC to a crawl and be VERY obvious.
...

This is NOT true. Programs can read and write to RAM not owned by them. Nice programs don't do it, but programs can do this. You need to know something about the data you are looking for, it won't be nicely labeled 'secret_key:', but it is not impossible to find and extract. I have done this (with other programs, not bitcoin) on both windows xp and 7.
