Spanish to English Bus/Financial Business/Commerce (general) Giving presentations

Here the text talks about avoiding 'classic tags' in presentations such as 'en definitiva' and 'un poquito'. My problem here is if I translate these as 'all in all/all things considered/in short' and 'a little (bit)' would it make any sense? It doesn't particularly ring a bell with me as I haven't had to sit through many presentations, and maybe the equivalents in English presentations (UK audience) are totally different. Any advice on this one would be welcome! Ta.

Otro elemento que debe controlar la persona que expone es el gesto. Es recomendable exponer con una expresión facial ligeramente sonriente, no forzada, que denote relajación y que haga presuponer que estamos convencidos de lo que hacemos y de lo que decimos. Asimismo, con nuestra voz utilizaremos varios tonos, evitando caer en la monotonía, acompañados de palabras dotadas del máximo sentido y tratando de no utilizar las coletillas clásicas como:*** “en definitiva”, “un poquito”, *** etc.
