First off, do you use TWX with Swath?
If you do, you can get a wide range of scripts at
http://www.grimytrader.com. Download the scripts into your twx/scripts folder.
If you are going to kill, use macro's. In my opinion it's the safest way and most effective way to do it. I have attack macros set to my f keys. For example, a y 9999 ^m, a n y 9999 ^m, q q a y 9999 ^m l m n t ^m c, or q q a n y 9999 ^m l m n t ^m c. These are the four I have always set. The last two being used for planets, I have to be careful with because of there are two planets in sector, i'm screwed. I'm no way near good at killing when comparred to others out there, but I find this is the best way to start. To set the macros to your F keys, you need to first make the macro and name it, then go to triggers and set a key to trigger the macro you made and named in swath. Just remember what keys you use as triggers,and always use those keys.
As far as gridding scripts go, the best public script out is Rammers twarp gridder. It's the most used by far. It has tons of options on it, and can really make it hard to get torped with. There are several threads already done on this, and Harley did a good long post on most of the options that Rammers t-warp gridder has to offer.

Lastly, Planet-Port trade scripts. If you are wanting to do world planet trades, the only one I know that is public are Supg's and I BELIEVE Caretaker. Both are at Grimy Traders. This is not an effecent way of trading because it will use a ton of ore off of your planet to move around, but can be good to get some MCIC's of ports for later use. A lot has been talked about this as well in several threads.
O.k. this is the longest post i've done in about a year, so i'm gonna end it and let y'all start throwing your monkey waste at me now.
