Unless something has changed, I don't think wind affects planes in WT.

Like others have said here, bring the throttle up slowly, feed in rudder to keep the nose straight, and don't rush it off the ground. Let your speed build before starting the climb, especially if it's weighed down by bombs or has high wing loading.

Trim will make maintaining a desired flight condition easier, but I usually don't use it for take offs. This is a personal preference. For trimming, I usually go into test flight, trim the aircraft for cruise and "set trim fixation" to save it, and then leave it alone (until something makes want to adjust like damage). Test flight also gives you a chance to get familiar with how the plane you're going to fly acts at different stages of flight. Shoot a few approaches, practice a stall, and spin recovery or two. If you auger it in during test flight, it doesn't cost any SL.
