General question on how to "download" free games

[kjo]

For example from How to get free mobile phone games from your computer to your phone without paying data charges
Download Motorola V360 Games - Free Java Games from MobileRated

I also found this site HOVR - Tic Tac Boom - Free download

I've got the files on my desktop and then I transferred them to my mini sd card and then put the card in my phone..when I go to new application and install new. It sees nothing from the card.
These files are like name.jar, name.jad

I'm not sure how to get them to load to the phone as a new application even though they are free games.

Can anyone assist? thanks
this is a new venture I'm trying. Since I lost all my games somehow- need a few new ones.
Thanks!
edit...okay I think I figured out how to get them there...but when I go to play one it always wants data access and I tell it no. Isn't there a way to play any of these games without always needed to be on data time for it? sorry I'm just such a newbie at this.

Or does anyone have the blackjack, bejeweled, and pinball game that was originally on my phone that you could send me by any chance?

This is also a problem I am facing. Right now, I am trying to upload them via MPT but apparently that isn't an option. I have read numerous times about using P2KTools but my phone just locks up the application and I can't do anything with it. I am currently using the Sprint Motorola V3M and if anyone could give me a clue as to which folder structure to place the jad/jar files in or what application might work for it, I would be appreciative.
