There is a thorough guide on completing The Fremennik Trails quest at http://tip.it/runescape/index.php?rs2quest_id=79. Find which spot you're at in the guide, and you're good to go.

For cutting Yew Logs, my best recommendation is south of Falador. You can reach the trees faster by using Cabbage Port from the Explorer's Ring, and you would either use the Draynor Bank or the Falador East Bank. If you honestly think Runecrafting is fun, you can either try Air Rune Running in the designated world. You won't get experience for it, but you'll at least get money. As for lighting Maple Logs, I highly recommend a non-designated Fist of Guthix world. There will not be anyone around to distract or bother you, and once you bank, you can start lighting right away. For the city-based banks, you usually have to run out of the bank and move eastward before you can begin, but in Fist of Guthix, you withdraw your logs and you're already in a good spot to start lighting.

Completing the While Guthix Sleeps quest is one of the requirements before you are able to wear a Dragon Platebody. You can try looking around on the High Scores, but I think buying one is a lot easier. But then again, not all of us have 30M+ coins just lying around...

I actually thought Barrows armor lasts 20 hours before fully degrading? And taking that into account, you could repair your full Barrows armor hundreds of times before ever reaching the price of a Dragon Platebody, and it really doesn't take much effort. You can grab a couple hundred thousand coins, Home Port, walk about 100 paces to Bob's Axe Shop, and you're set to go. You can even get a discount of up to 50% if you have a decent Construction Level and a high Smithing level. O.O
